As many said here - it truly depends on what games you like to play. I have been gaming since i was a kid which incidently has become my profession now and I head the buying and marketing division in Geekay games for the GCC.
What we have seen increase during these lockdown times is the Nintendo switch mainly because it is more of a family console with its own set of games like the Marios , Just Dance , Animal Crossing etc. Playstation coming at very close with many game developers really focusing their games on this platform - you can really not go wrong with this console ( unless you want to wait for a much pricier PS5 in Oct/Nov ). Xbox has close to less than 5% following in the middle east partly because majority of the install base in the middle east is PS4 and you really wouldnt find much ppl to play with in multiplayer games in the middle east.
The best time to buy this will be during the Ramadan/Eid period as many brands are discussing on promotions at this point and as an insider i can tell you there is a possibility of getting an Xbox X for 1499 AED and Playstations 1TB are going to go at 1249 AED. A problem we are facing currently is a big shortage on Nintendo and Playstation consoles due to a surge in sales , which should hopefully be better by the last week of April. I would personally recommend going for the PS4 as of now if you can still get it of course.
