are you looking for straw cup or sippy cup? dear son has been using MAGMAG straw cup and Munchkin straw cup. MAGMAG is good as it has a handle for them to hold but it is not leak-proof. Munchkin is leak-proof but is abit diifi to suck the water from the straw (since it is LEAK-PROOF haha) so the baby need sometimes to 'master the skill'
If you're looking for sippy cup, i think Avent one seems not bad.
for cleaning, i think all are the same, have to take out the straw (for straw cups) for clean the straw thoroughly by using those straw brush. =)
