Depends on what you want to use it for, Hunting, target, scoped or open sights. Heavy baull barells and bedded thumbhole or target stocks will cut recoil, and make bench target shooting more comfortable, but makes a rifle too heavy to carry long distances. Light taper barells, with traditional stocks are light, easy to carry, and better for standing shooting, and make for an ideal and powerful deer gun. Also you have the choice between mauser style controlled feeding reliability, or a bolt mounted extractor (better if you want to chamber single rounds for target shooting'
The savage and CZ varmint rifles have fantastic triggers and area about as accurate as you can expect from a < $1500 rifle, the Winchester and remington are a little pricier, but dont really have any edge in accuracy, have a plain trigger(no accutrigger insert (savage), or push forward to engage target pull(CZ)) and the fit and finish seems to be better. I love marlin lever actions, but would be a little hesitant to shell out a lot of money on a new cartridge where availability is low and assurance of long term support is still up in the air. The leverrevolution bullets are not available to reloaders yet, you could load the cases with standard RN bullets, but that kindof defeats the purpose. If you like lever actions, one in 30-30, 45-70, or even 44mag already has good component and factory load availability, and 30-30 is no slouch, more deer have been taken with this cartridge in N.A. than any other, but 150+ yard accuracy is not it's strong suit.
As others will probably say I agree with the idea to find one that looks good to you, shoulder it, fire it if you can and weigh that in with your decision.
