If you get the 8gb model use Microsoft edge, it has some amazing features including sleeping tabs, which will save you quite a bit of RAM. For me, I can watch 4K video, play minecraft with shaders at 165fps, and render video with premiere pro without using the full 8gb of ram

Rectangle allows you to window snap easily, the microsoft outlook app is one of the best email clients for mac, Microsoft edge has Vertical tabs and bing ai chat which can summarize webpages, and stage manager makes managing app windows easy

M series mac’s get way better battery life, but with the Intel ones you can run Windows natively
