Common sense would seem to suggest otherwise, at least in the case of the 190. There was a thread a while back discussing the degree to which a radial engine is more battle resistant than an inline, but I don't think anyone doubted that the radial was ultimately tougher. And the 190's airframe should have been at least as tough as the P-51's. Tank designed it that way.
The P51 had a reputation for being vulnerable to fire from below hitting the cooling system, though whether it was in fact more vulnerable than other liquid cooled fighters, or whether the reputation came about because then straffing duties it assumed later in the war more often placed it in harms way, I don't know. In either case, it's a problem the 190 wouldn't have had.
