I would go with the AMD, you can upgrade later if your budget allows to a 6 core Ryzen 5600x or even a 12 core 5900x (if they ever become widely available) so you have at least an upgrade path on the AM4 socket. With Intel you will be way more restricted without having to buy a new Mobo.
If it is for casual gaming with a 1650 4gb card the Quad will be fine for now, get more later and sell the Quad. The GPU will bottleneck any 6 or more core CPU anyway..... go with what you are happy with and enjoy it, you do not always need more, bigger, better to enjoy your PC !!!
P.S. having 16gb RAM in dual channel not 1 stick in single channel will do more for your games than 2 more cores will.
