Never driven a C63, just took delivery of my 15' GS 450h F-sport...and its amazing. Correct me if I'm wrong, the C63 is an 8 cylinder? Performance might be over to Mercedes here, but tech and hybrid-tech is seamless in the 450. I'm just getting to know all the intricate details on mine, but I'm slowing learning that there really isn't much that Lexus hasn't thought of to make a creature comfort. My recommendation is to go test drive one.

Haven't driven the C63, but have tracked both the older E63 (v8) and GS 450h, and their lesser versions battle in the same class. Agree you should test drive it to see if you can accept the performance deficit (and the eCVT). The GS felt to me like it's standing still in comparison, but of course, some choose it for that very reason.

No matter what anyone says, the very best thing to do is to test drive both (especially if you're fortunate enough to have a 4GS hybrid being sold at your local dealership!). It really bowls down to what you value and looking for more in your next vehicle - power vs efficiency.
