I've had hamsters, gerbils, bunnies and when growing up I did have a rat!
then dd around 5 - 6 years ago found a guniea pig rescue group and I got her a gp - WOW! what a difference! Gerbils and hamsters are nocturnal, and are often biters - they are small and cute to look at - but you have to be dedicated to socialize them - or they become mean...

this link tells a lot about cages, and also has lots of other links on the right and left side - and dd has "trained" her guinea pigs! Its amazing! and they absolutely love when they hear dh come down the stairs, they start "screaming" whheeek wheek - because he got in the habit of giving them a baby carrot in the morning, and he encourages them by wheeking and whistling back!
when I come home from a shopping trip - they run around and wheek, because they learned its usually the grocery store and I buy different "greens" for them! They love dandelion greens, Kale, and a curly lettuce I think its endive! (it runs about $1 these greens - once or twice a week - I bought the tupperware container that keeps greens fresher longer, chop them up and store them, that way dd could easily get greens for them all week!)
and dd teaches them to follow her, or come when she whistles, or they just sit in her lap when she's had a bad day, or a good day.... if I knew then what I know now, I'd have bought guinea pigs sooner!
so I vote for GUINEA PIGS!!
