The high end iMacs are quite nice, as long as you don't mind their all-in-one nature (including the monitor obviously). Back in the day I might have suggested Hackintosh, although that's always seemed like quite a hassle to me, and certainly less appealing now Apple are moving over to ARM.

If I buy another Apple laptop it'll probably be a 16" Macbook Pro. In fairness to Apple I usually get at least 5 years out of one of their laptops so can generally live with the premium.
