Curious about the difference in what I’d hear on different tonearms

I’m relatively new & most of the numbers & concepts people talk about are still over my head. I do basically understand that different tonearms are a better match for  certain weight cartridges. To reduce the variables I have a Lyra Delos cartridge & a Rega 330 Moth tonearm & I only want to compare up the Rega models without advice thrown in about different cartridges.  Here’s my question, with that setup & all other things being unchanged, what actual difference would I clearly hear if I changed the tonearm to the Rega 808 & then between 808 & the 2000? Please-“I’d never use a Rega... get an ABC model 1234”, same related to the cartridge or other parts of my system... it’ll just confuse my understanding of what you’re teaching me.

Thanks
