No.
Especially when the MG151's are terribly mounted and only carry 1.25x the ammunition load of the single installation. I never said that they were equal, but I would not put the difference at 'substantial'. The C.205 has a considerable but not major advantage in firepower over the Bf 109G-6. The G.55 has maybe 2.75 the effective firepower of the G-6 but they still both have close to the same firing time, with the edge again going to the stromboli...
They have the same capabilities. The G.55 is just better at some and the G-6 at others.
Sorry, I have to disagree again. Just because in theory the mounting on the 109 is better ( in my opinion only for shooting at very close distances), it will not change the facts I stated. The 205 still does damage quicker and much more of it in total. Beside that, there could be situations where you might just miss with the 20 mm in the 109, but you still might hit with 1 of the 2 in the 205. Shooting out of convergence is not always a bad thing. The G.55s setup is the best of both worlds. It's true that the firing time is very similar, but you forget that the targets will be destroyed 3 times faster. That is a huge advantage, and thus the G.55 is much more capable at killing targets, both in time and quantity.
I don't see D or N Jugs anymore. But do you see any more P47's as a whole than you used to? The M jug definitely took usage away from the rest of them, but did it take a significant amount of usage away from other planes? The M 'doesn't count' as it's a better version of what we have, while at the same time it's a perfect example because it's one of the better planes in the MA today, and it's still not all that much more common than the P47's used to be. At least from my observation.
To be honest, yes, I do see more Jugs around. And a lot more used offensively as fighters. And those are like 85% M-Jugs. And it most probably cannibalized a lot of D-Pony usage (see Lusches most rescent ststs) among other planes. And I think you just made a very good point for the G.55. Indeed the M is no revolution for the P-47 lineup (think as N-Jug minus 500lb... it's not that much of a difference in 14-15.000 lb planes), yet it has tremendous success...I see no reason why the G.55 being much better than many "similar" planes, shouldn't make a noticeable impact.
Another example would be the B-239. It might be the best low/slow fighter in the game... the only competition it has is the A6M. How often do you see it?
The P39Q is another example. It's a perfectly capable, well rounded MW aircraft. Every time I take it up I marvel at how good it is, compared to how much you see it. It always does great in FSO. Yet how much do you see it in the MA?
I agree that the P-39Q is way underused. There are many reasons for that: Difficult rear views for instance, but the main reason is that almost no one takes the time to get used to the tater. It has a steep learning curve, and most just give up on it, before the plane can deliver the results.
As for the Brewster, it does not do too shabby for a strictly EW plane. It does much better than many of it's contemporaries.
It's not a well rounded plane overall. It has no redeeming aspect, other than it turns OK and has 4 20mm cannon. Any plane that can turn with 4 20mm cannon is popular in this game. I mean, look at the Hurricane MkIIC...
Just for the record, the Niki has twice the usage of the Hurri - I guess 50 mph speed advantage OTD do make the Niki a more rounded plane.
And compared to the P-39Q, a well rounded plane in your opinion, the Niki is the superior plane overall. Yet it has no redeeming trait?
