I was considering the CR-6 when it was being crowdfunded. I ended up going with the Ender 3 V2. There are comparison videos online which will show the differences. They are both great printers and if you go with the CR-6 I am sure you will be thrilled with it.
I now have 2 of the Ender 3 V2 printers. It has been a great printer for my hobby use. I make a lot of things for the shop and my kids make all kinds of toys, statues, and collapsible swords. I think the most significant feature you want to look for in Ender printers is the auto bed-leveling feature. It really helps get cleaner prints. Some printers do not come with auto-leveling, but you can easily add a Creality auto-leveling kit (CR Touch) for about $50. That CR-6 has auto-leveling built in. I would also replace the stock plastic extruder with a metal extruder. You can get metal parts on Amazon for under $20 and swap them out. The last inexpensive upgrade would be to change the Bowden tube to Capricorn. Capricorn tube feeds the filament much better than the stock Bowden tube. There are upgrade sets on Amazon that have Capricorn and metal replacement parts.
I personally find Ender printers to be great. Many of them require a lot of tweaking and minor adjustments to get them working well. When assembling, they take some time and thought to make sure everything is squared up properly with the frame. Once I added metal extruder parts and a new Bowden tube my print quality went from good to great.
Here is my printer in my workshop. I keep it in a ventilated flame-resistant tent. My kids print things that take 48 hours. I don't trust these things running at 400+ degree temperatures unattended, but have never had an issue.
