I don't think that is quite accurate, Corvette hasn't exactly been setting the world on fire since their GT2 switch. They were competitive sure, but never to the extent that we are used to seeing them in the hayday of GT1. They were even sorta out of touch with the winning crew work for a bit, lots of tripping over themselves. While its I think only their 2nd try at Le Mans with GT2(sorry, GTE Pro) and already landed a win, they haven't really been the fast car as they are used to. Ferrari and Porsche have been at this for a while, building fast, turn-key car that can be run competitively by any fast driver. And if the team is competent they can contend for the win. If you don't have a fast driver, Ferrari/Porsche will supply them....Its usually one Corvette team(or BMW) against 3-4 Ferrari/Porsche teams that are all fast and all can win. And for many of the customer teams, they don't have to worry about the development work, just prep(which is still a challenge, of course), but in the same token the need for the vast resources is not nearly as bad as running a prototype operation. Remember the last big win from Corvette in GTE Pro/GT2 was PLM last year, and that was more due to the faltering Risi than Vette being outright faster....Now this race at least shows that finally Pratt & Miller have gotten their pit work well sorted, and their car is reliable(they blew motor last year at Le Mans IIRC, and have issue with motor at Sebring this year). Maybe they will be back to the dominating ways, but somehow I think that won't be the case...BMW is plenty fast, 458 is faster, if not more fragile, much like 430 was early on. Given time they will also get better. You can count for Porsche to improve the GT3 also....
Picking between GT and LMP I'll always go with the latter, but the current GT classes are very exciting to watch....
