Well, I have both a Tele and a Strat. First off, they sound very different. Teles have a bit more twang or bite. Clean sounding, they make great guitars for country and blues. Distort them and they are "icey" for lack of a better word. Bottom line, they are a work horse and jack of all trades. But what guitar isn't? Strats? Well you own one so you know what it can do. With the three pickups it, too, can do just about anything. So there, I hoped that helped. I use both very frequently for recoding. I have a Jay Turser copy of an ES335 (with humbuckeres) which I use, but not as frequently for recording. Why? I don't know, the Tele and Strat just "feel" better. The ES335 copy does more of Jazz style warmth, which I like, I just don't record in that genre. But the actuall Gibson ES335 served Chuck Berry and BB King well. So, each guitar is unique. And each guitar player brings out something unique from each guitar.
Oh, BTW, can you ever have too many guitars?
Peace, Jim
