I've had all three for a while now, and I find the one I put on the most is Television. I like how it has a really overt sense of humour, and I think the playing and songcraft are excellent. Also, I like Verlaine's talking-singing voice a bit more than his histrionic singing, I'm guessing that's an evolution for him as I haven't checked out his solo LPs yet.
I got The Blow-Up a few months ago at a local record shop. The dude at the counter pointed out how expensive it was (like I didn't know that), told me it was basically Marquee Moon but out of tune, and gave me a discount without my asking for it. Weird. I like it anyway.
Anyway, as others have said, it's great there's a Television community here.
