For rectifiers, if your budget is tighter, go for the EML Labs 5U4G Mesh. Terrific tubes, and reasonable. My personal favorite is the old metal base GZ-34-- mine are from 1957 bought as new-old-stock. It is an ugly ugly stubby tube, but there's no denying the sound. Difficult to find a matching pair, and they can be pricey. If you have unlimited funds, go for the Takatsuki 274B. Great tubes. Best in class. Skip the Sophia and PSVane tubes.
Driver Tubes: I've tried more driver tubes than any other. I've settled on Tung Sol 6SN7s with round plates. I've heard nothing better and they're the most reasonable of the tubes to purchase. The worst tube I've heard in this category is the PSVane 181s. Avoid them.
Power Tubes: How much do you want to spend? I have the Takatsukis. No complaints at all. They are not cheap in any way, but the sound is magic. They are as good as you can get without buying vintage Western Electric 300Bs-- which can run $10k. Western has begun manufacturing a new run of 300Bs for the first time in 20 years. I have a pair on order, when will they get here, who knows? Elrogs are just as good as the Takatsukis, at a lower cost, but mine blew up after a year. They reportedly have solved the problem, but I'm not taking that chance ever again, since they didn't replace my blown tubes-- so Elrog is dead to me. The one tube I'd recommend if your budget is limited is the EML 300B Mesh. Beautiful looking tube, *only* $1000 dollars/pr. And about 85% of the sound of the more costly options. You won't be disappointed. I would avoid the Sophia 300B, personally. I preferred the EML.
