I used Elixirs for a few years after my Taylor 612ce came with them. Started using them on all my guitars. I liked them, the tone was good and they last. Switched to Thomastik-Infelds and never looked back. They sing. I don't think they are great for rock, but jazz and blues they are the best.
I have T-Is on my jazz-box, and Elixirs on my main solidbody. I like 'em both. The Elixirs have such a smooth feel and mellow tone, I have a hard time playing on normal rounds (they feel sticky now).
The T-I flats on the jazzbox are great. They seem to intonate better than other brands - the needle on my tuner doesn't wobble around as much. I'll have to try some lighter T-Is on my solid. Which ones are you using?

I have been using George Benson's Jazz: Custom Flat Rounds
For my Gibson Tennessean.
I use Power Brights for my solid body guitars. I prefer the heavy bottom series for sustain. The TI's really sing.
I like the Plectrum's for acoustic. I switched from Elixir's earlier theis year and will probably never go back. The T-I's feel soft, but play hard.
