The instructions aren't great. There have been minor design changes to production units not covered in the printed instructions. I honestly didn't look at the SD card to see if they were updated there. They don't really cover the importance of loose assembly and final tightening to square it properly. I put a drop of PTFE oil in the bearings and work it in and lubed the lead screw lightly. Little things like making sure the eccentric rollers are properly adjusted can make a big difference in print quality.
If you think logically about it it isn't hard to assemble with the given printed instructions. Just remember it's not a race and double check the already assembled sections.
Bigtreetech makes great 3d printer controller boards for their price (albeit with hit or miss quality) with many of them being direct drop in replacements, and probably their biggest selling board was/is an Ender 3 replacement board, the SKR mini E3. I own a few mini e3's, and they work great. It's just that the product is no longer as relevant as it use to be. Creality updated their boards across the CR-10 and Ender 3 models, and even the base model Ender 3 now comes with a 32-bit board from the factory. Although the SKR mini E3 still has a few more headers to connect to, the biggest issue was always the original Ender 3 having an 8 bit board and it's extremely limited Melzi board memory which hampered adding new features when new firmware updates arrive, and that is just no longer the case with the new Ender 3 boards, making the SKR mini E3 less relevant.
Anyways, Bigtreetech came out with the Bique to offer what is essentially an Ender 3 but already running their SKR mini E3 inside, and now as I stated before, with even the base model Ender 3 coming with a 32 bit board, this printer no longer really offers any value over even the base Ender 3, since any of the small additional features can be printed out or even purchased and added to an Ender 3 for less money. For example the steel spring bed, can be purchased and added to the Ender 3, but I think that you will find that a glass bed is better anyway
And as far as the fan noise goes, you are most likely also going to have that on an Ender 3 as well, or any other Chinese printer at this price point.

It offers several things over the Ender 3 v2:
Color touchscreen. E3 v2 is only color
Better quality mainboard
Plug in port for a BLTouch, so you can install one without having to crack open the mainboard box and run the wire
All metal extruder that won't break in six months of use.
I wound up buying a used Longer LK1 off eBay for $204 directly from Longer. It appeared to be a damaged box return from Amazon, but the contents were brand new. Basically the same basic printer as a Creality CR-10 size wise.

I can't really compare the two, I've had constant issues with keeping the bed leveled on the ender 3 pro. I bought it as a certified refurbished printer from Comgrow, so that may play a key factor in this situation. So far I'm having better luck with the LK1. I just bought a enclosure to put it in, running into issues with humidity in my workshop and having the E3Pro in a enclosure with a plug in rechargeable silica dehumidifier really helped for that issue. I printed out a filament guide for the LK1 on it this evening, and noticed slight shrinkage/ warping in one spot on the print, so the enclosure will help with that too
