Well you have some options and it depends on your budget. Use self leveller and get it to manufacturer tolerance for click vinyl. That way you will have a warranty on the product. This will be the most expensive way to go Don’t level, install click lvp and have the joints fail after a bit and have floor look like crap after first renter and then have to redo it. Cheap now but more expensive in ling run If you don’t want to pay for levelling and don’t mind seeing some deflection in flooring, go with a glue down lvp. They have some good 5mm thick ones that have a 20ml wear layer that are reasonably priced. Use a releasable adhesive so you can easily swap damaged planks out after each renter.

I laid 2000 sqft in my house this year. It’s great product. No need to acclimate - the issue you’re experiencing is with your subfloor. Since this stuff floats, if the subfloor is not level, it will dip into the low spots when you step on it. A small dip isn’t a big deal, but if large enough it can cause boards to pop out.

I install a lot of SPC. Some WPC, the price point deters a lot, most people are putting this in a basement they don’t use. The WPC feels much nicer underfoot, and feels like it will last longer. (Especially floating) SPC is harder and more durable but the locks tend to snap easier, whereas the WPC can sustain more deflection without failing. If your subfloor is perfect both are fine, but I would personally put WPC in my own home over SPC. More on reddit.com

Floor&Decor like HD or Lowes has good and bad product. They source from the same companies & places everyone else does. There really aren't that many places this stuff is made... The devil is in the details. See if you can find the real manufacturer name on the nucore box. If you want SPC make sure your prep is really flat and solid. If your floor is a little wonky get wpc that can flex. Get 6mm - 8mm total thickness and no less than a 12mil wear layer. I've used 12 and 20 and honestly both look the same after 2 years and I have a 40lb cattle dog. Repetition wise if you get EIR / IRE you'll have a nicer looking product but less repetition. 4 unique planks with flipped versions is usually enough if you lay it right to avoid repeat. Watch out for designs with very distinctive knots... Those can really be glaring when repeated. Backing according to everyone I've asked doesn't matter, but foam is less likely to have issues and cork is quieter. Good luck. More on reddit.com
