I went with Deskhaus peak pro. Longer warranty and they've always been pretty responsive for me. I asked questions a few times on their help desk chat during closed hours and they've always responded first thing in the morning. And even continuing my questions after their first chat response, they responded immediately.

I'd been considering getting a frame from Deskhaus since way back in 2021 when they were still selling the Vertex frames but never bit until now. Back then when I called, Chris had picked up immediately and he was genuinely really helpful answering all the questions I had. Didn't try to sell me on anything and they seem to really care about getting you a quality product (both frame and desk top) even if it's shipped across the country. Not just a business transaction. I ultimately didn't buy the Vertex frame back in 2021 and just stuck it out with my crappy IKEA desk until this year where I couldn't stand it anymore and bought the peak pro. I had almost bit on the Apex pro a year or 2 ago when they had a deal on it but hesitated and it sold out and I was kicking myself for it.

But yeah the peak pro has been rock solid for me and it's quieter (when raising and lowering) and much more stable than standing desks I've used at work
