Well it sounds like scoping a lever is sacrilege and not ideal...
Hmm thanks for the advice so far guys, I'm going to handle both and see which stock I prefer, on looks alone I'm leaning towards the Henry un-scoped.
always take what people say with a grain of salt

remember that in the end this is
your first rifle so get whatever
you want.
i
personally wouldnt scope a lever action because of the 'style' of gun it is:
a lever action is best as a fast (fastest action, my lever nut friends can work a lever as fast as a semi-auto) and handy little rifle, ideally suited as a brush gun used with iron sights, very quick to bring on target and fast follow-up shots. over a hundred years now and theyre
still the best close-in brush rifle, and bear defense in the big bores
but in terms of accuracy, they will almost always lag behind an equally priced modern bolt action. a big clunky scope on it it also ruins the rifles handling, and like prosper said the stocks arent really designed for a good cheek weld with a scope so youll end up having to put some sortof aftermarket or crafted raised comb on it. the calibers that classic lever actions come in arent exactly the best suited for accuracy either (although im sure a handloader will argue and show a <1 MOA group with .45-70 this is far from the norm), although the Hornady leverevolution ammo is going a long way to remedy that. the Browning BLRs come in many modern calibers but theyre not a 'true' lever action, theyre more like a bolt action with a lever operated bolt
thats not to say that you wont like it with a scope, but it might not be the tack-driver you may be expecting. really up to 100 yards most people can do a
lot better than they think with iron sights -- try them out first and see how you like them before you scope it. i also find it a lot more fun and more of a feeling of accomplishment to target shoot with open sights offhand compared to off a benchrest with a scope. another thing to consider is upgrading the iron sights on it, keeping the traditional lever handling but with better accuracy.
that said chalk up one more vote for the Henry Golden Boy. cant get more traditional styling than that - pure class with the octagon barrel, straight grip stock and brass receiver. the Marlin is a nice looking rifle but it definitely takes a second seat to the Henry.
