Whats the advantage. (Cams)

The stock 340 cam is .429/.444 228/235° @ .050 268/276° advertised with 44° of overlap.
The XE262 is .462/.470 218/224° @ .050 262/270° advertised with 46° of overlap.
The difference is the rate of lift and the duration the valves are open in relation to the higher lift but I don't feel there's going to be much difference. Not because the Comp is that bad, but because the stock 340 cam is pretty good.
