Upgrade from Mojave to Catalina

Has anyone recently upgraded from Mojave to Catalina? Has it got any better a year later? I’m using a 2015 MacBook Pro 128gb with 8gb RAM still on Mojave and was hesitant to upgrade because I heard there’s supposedly a lot of issues with Catalina. Is Big Sur any better? I also rely on Adobe apps for work which take up a lot of space so would this cram my computer up?
