Firstly, have the expectation that despite them saying 150/300/650/1200/1800/3000Mbps, you will NOT get those speeds

its a bit of rounding up, and also counting download and upload together, and being in a perfect lab environment with 0 interference

like, a typical N150 adapter will get you real world speeds of about 38Mbps, but hey they are cheap, like less than RM15

for wifi 6, it really should be AX1800 or better
the lower tier ones like AX286/300/900 are not so great, especially the 286/300 ones as they rely on AX 2.4Ghz that not all routers support

of course, the price is higher for those

And, if it is a desktop, please get a PCIe card instead, brand doesn't matter too much as most of the AX3000 ones out there use the Intel AX200 chip (well, the big brands like tplink/asus/dlink/tenda/totolink), it is a very solid choice
~RM100 for one
