Hi, and welcome.
Another vote for Blackguard Flat 50 for what you describe. In my hands, at least, it's capable of thicker, "hairy-er", and more bite than the Yardbird.
Both clean up really nice (can't get at clips while I'm at work, but I'm guessing from what Twinfan says that I'd agree with him).
I've got both. I choose the the BG teles when I'm playing in a situation that wants one, or possibly two, guitar parts that involve blues licks or similar that are going to be "featured" as "hey that's a great guitar part" in the mix.
I choose the Yardbird tele if I want a nice 60s pop rhythm guitar, for example, or if I'm doing classic rock stuff where I'm layering lots of parts and I want them to blend without getting too muddy, or if the tele part has to cut through some other parts with humbuckers...
I choose either for an actual lead/solo part.
If I'm playing ZZ Top or Black Crowes I definitely pick up a BG guitar. Something like The Seeker, either could do, early Page/Beck, the same, but I'd lean towards BGs with my amp settings (even though I think the Yardbird tele would be more "authentic"!!)
I do actually find the Yardbird set more versatile than the BG set, but I prefer the Blackguard Flat 50 bridge pickup. It just seems a bit more "in-your-face" and responds very well to vol/tone control fiddling, which I'm guessing is what you'd need on an Esquire.
I've not tried Country Boys, but I kid myself that I've got enough overlap with the BGs and Yardbirds (to save me getting another set and a tele to put them in!), so I can't really comment on those.
Hope that helps some! :D
