A Conquest II has more space than 421 but now you're talking a LOT more $$.

Pilot number one has no tolerance for breakdowns, delays and AOG situations so he spends more for MX.
Pilot number two is OK with unplanned delays, breakdowns and AOG situations so runs the plane till things break.
Pilot number three is somewhat in the middle.
I am like number one so I spend a lot on preventative MX. It's still cheaper than a C90 for 100 hours a year. There has to be some point of diminishing returns. Even "new" stuff breaks.

So the 340 can be a bit faster with the same engines. 414A has an entirely different wing than a 340 or the 414 or the 421. It really likes being up high where is might actually be faster than a 340 or about even. Never flown a 340. What's the cruise speed at 65% at FL220? 414A with winglets will do about 215knots.
Book speed is ~205 for your setting / altitude in a 340, and that's about what I get. I've heard of others claiming higher. You could certainly remove some extra antennas and strobes (relative to my plane) and do better.
My comparison is to the 414, as you say the 414A has a different wing and I am not to familiar with it. Based on RAM's numbers for a 340 RAM VII to 414 RAM VII, the 340 has a 10+ktas advantage. Their comparison to a 414A is not at matched conditions, but does show the 414A about the same or slightly better than the 340.

True Tom, the owner has to apply some common sense or "cents" in some decisions.

Don, for this scenario lets say a budget under $350,000. More space compared to an A36. We'd like to be able to carry 5-6 comfortably about 250 NM and a few trips that could be more than that.

As a new owner with <25hrs multi time and low total hours, my hull rate for the 340 last year was 1.5%. For the $400K hull rate he refers to, that translates to $6K, plus liability, which is less than his $8K-$9K number.
His $12K annual with no squawks is also high. But as rough numbers, I didn't think the video was too far off. Save a few AMU here or there, and spend it somewhere else.

I only have 225 hours of multi ( most of that in the last year). With $350k hull, I payed $7,700.00 last year and will pay about $7,000.00 this year. I was able to get a quote with my plane based on a hard surface runway instead of my grass strip and it was $4,800.00, so I am being penalized about $2,000.00 for the privilege of having the plane at home. I guess I can live with that.

Thatcher, I think you're looking at the best options for that price and mission. You're not going to get anything with more speed at that budget, except for perhaps an Aerostar 700 but you will give up a lot of cabin space and the A* cannot comfortably sit 6. A C421 is really your best fit. A C340 while nice too you will find is best for 4-5 total. Most C340 drivers only have 4-5 seats installed as it makes it much easier for cabin entry. I had the aft left seat removed when I flew one and found it much more reasonable with only 5 seats. The C421 can very comfortably seat 6 and do your mission perfectly. Most flight plan for 200-210kts but they are capable of faster if you run them higher and a little harder.

That's a great point Tom. I will say though, we operated a C90 for a few years and the thing was damn reliable... reliably expensive but reliable. The maintenance events were eye watering but I can only think of one unscheduled issue. I just wonder if some of the savings of a 421 over a C90 goes away if you put a dollar value on the time to shuttle the thing around to various shops dealing with the myriad of things mentioned in the thread. For the record I just love the 421C !

We'd like to be able to carry 5-6 comfortably about 250 NM and a few trips that could be more than that. Six with luggage is doable but tight in a 340, and that's with less-than-FAA-standard people. Loading up is a trick, as the last seat has to be pulled forward to get in the door, then you can slide it back once the door closes. You can be up against the zero-fuel-weight, so you would want to seek a lighter plane. With a full load, I'll get about 2.75hr max legs with reserves (~500nm). I'd say it's good for occasional traveling with a family of 6, and certainly more roomy for adults than an A36. But if carrying 6 is the primary mission, you want a bigger cabin.

who is your carrier? I have about 1200 TT, 200-250 ME, and I'm paying about 8k on a 400k hull. my biggest gripe is the annual recurrent sim training. there aren't many options for ME piston sims, and none of them are the same as my airplane. i'm way better off doing an annual IPC.
