which guitar is better??

standard telecaster or epiphone sg 1966 limited edition?

is because i'm looking for a good guitar,, with a good sound,,
i usually play a little bit of everything.
Define better. If it were me I would lean towards the telecaster of course I assume you are buying a MIM tele so I would make sure I played it first.
1990 Gibson LP Studio
2007 American Deluxe Stratocaster
2006 Taylor 510-ce
Fender Geddy Lee Jazz Bass
Mesa/Boogie DC-3
Based on who you have listed as your favorite bands and favorite guitarists on your profile, I would say the SG would probably be better for you. But go to a guitar shop and try them both out and see which one you like better.
What tone specifically are you after? Though comparably iconic and good, their very different guitars.
