If you have corny kegs, they work fantastic for fermentation, lagering, you name it.
Kegs give you the ability to transfer beer between vessels that have been purged with CO2 using counter-pressure; completely eliminating oxidation worries.
Glass carboys will work fine as well, they're just a little more delicate and require more careful transfer/racking procedure to try and avoid oxygen as much as possible.
There is some disagreement on this, but I feel that any time you have beer in a vessel for over a month, you shouldn't use plastic of any type. I feel that there's too much oxygen permeability in plastic and you will get oxidation.
