I did some checking not long ago about the C-hog, and compared it to the spit16 we have now. The l-gay is now where it was then, basically second runner up, but by a large margin. The first plane was the chog. Now, a couple of things to consider: there were many many many less subscribers back then, there were less planes (a LOT less planes), so less choice, which means every plane will have a higher % of kills over the same plane today, simply because there's more choice now and folks will filter out into other rides.
The C-hog of its time was getting 20% of the kills in the MA, back when it was perked. It was leading the pack by MANY thousands of kills every month, over the L-gay and the N1k2. Now it is the spit16 which has many MANY thousands more kills than the L-gay, and then the 3rd is still the N1k2.
The LA7 and N1k2 have about 10,000-15,000 more kills per month than the next closest "best planes". The spit16 has 10,000 more than the LA-7 per month.
That's how many kills it's getting, AND that's *with* many many more planes than the C-hog had during its time.
Spit16 is the equivalent of the C-hog, but the HOs are more survivable (only just barely) and it's slow as s***. That's the main difference

(that, and lack of ord, lack of carrier capability, etc)
