Well, ideally the best guitar for me would be a gold top Les Paul, with a bolt on neck, a Bigsby Tremolo and 2 P90's... since those are my favorite aspects of all guitars... though that kind isn't very common and I've never actually played one...<.<
So I'll go with the Fender Jazzmaster... the long scale neck makes it a bit hard to bend notes... especially since I use heavier strings... and the general width of the neck is a bit thin... but the longer neck gives it better bass response, which is the perfect with those lipstick pick ups, which already give you very beautiful glassy high and mids, gives it quite a nice range of sounds... even with just 2 pick ups... though the mid range output on the pick ups does weird stuff occasionally... but it doesn;t hurt to have a tremolo...<.<
Though out of all of the guitars that I actually own... oddly enough my favorite one is my 1960's Univox Hollowbody... well I think it's a univox... but it's frets are worn down to nothing, it's made out of ply wood, the wiring was done wrong and the action is extremely finicky... I have to constantly adjust the action... but it sounds amazing... I don;t even know why... it just sounds great...
Just such lush clean tones... especially the neck pick up... and blistering rock tone, just with a bit of gain... it's the perfect guitar for me... even if it plays like ass...<.<
Also the Teisco Spectrum 5... because look at that thing...<.<
