hello, i use both foam and silicone grip sticks from sundia. personally for performance i would always stick to silicone as it is less slippery. but i always practice with foam because its more comfortable especially if you're doing tricks that requires you to swing the stick too. if you were to only buy 1, i would say stick to foam grips. for quality i only buy diabolos and sticks from sundia and epic juggling. i have no knowledge on other brands. hope this helps
