All our Panasonic plasmas (v10, s10 and c10) do get IR, but I quickly got used to it. It gets mostly flushed away with normal use, anyway. If you look for it, you'd find it. All had exhibited some black level rise, but we've learned to keep it manageable through appropriate picture settings. The plasma advantages of good colors, motion resolution and viewing angle are still there. Keeping frame doubling enabled also minimizes my eyestrain from the inherent plasma flickering (I acknowledge that very few people are sensitive to this).
We also have a couple of LCDs (panny u20 and samsung b550) that do their jobs well. SD content obviously don't look as good as the V10 in these TVs, and I think that's more because of the poor scalers in lower end TVs than the fact that they're LCD TVs (the C10 and S10 also don't do very well with SD). Static contrast and motion resolution aren't as great, but they kinda make up for it with excellent image sharpness. The viewing angles are surprisingly quite good too (a lot better than older LCD TVs). I like the fact that the screen doesn't flicker with whatever material I feed it. We're also fortunate that both models don't have noticeable uniformity issues.
I can comfortably say that I can live with either technology. The same way that I could live with a diesel-fed or a petrol-fed vehicle. They both have their ups and downs.
The current flagship LED-lit LCDs offer amazing PQ, imho. It's not just because of panel advancements, but also because they are equipped with the best processors. If money was no object, I'd probably go with one of those.
On the other hand, with my limited budget, entry level to midlevel LCDs and Plasmas suit me just fine.
