Cartridges better than Colibri XGP?

It's time for me to change my cartridge ( I'm using a ZYX Airy 3 Gold) trying to improve my analogue source. So, I'm using a DIY suspended turntable and my technician believes in low mass tonearms - low mass / high compliance cartridges combo. I know that Colibri is a major cantidate but with which tonearm? Do you believe there are cartridges better than colibri? Which would be your favor tonearm/cartridge matching? Please give me your opinions.
Thanks a lot in advance.
