Sage bambino

Hi all, iv had a sage Bambino for a couple of years now and it seems to be great, I use 200° coffee beans that I buy already ground and the coffee tastes exactly like it does in the shop, my question is, what would I benefit from a more expensive machine? I see all these fancy machines on here and think mine tastes great as it is. Recently got a bottomless portafilter as my old one got a bit mankey and I want to say I can taste the difference but for the better (I might just be telling myself that). Just curious to hear people's opinions on more expensive machines appsed to my relatively bottom of the line one 😊
