Blade glide has mostly to do with rocker radius - an 8ft radius will have more glide than a 7ft radius, and generally with a 7ft radius turns should be easier, but turns and spins on a higher level blade regardless of rocker radius may be more difficult because the length of the spin rocker is shorter and the drag pick is larger - requiring better balance on the blade, which is usually more difficult for a beginning skater to achieve.
A higher level skater is more apt to be able to skate on anything (I've seen skaters do doubles on hockey skates and plastic rental skates). A lower level skater may find themselves constantly catching/tripping on the larger drag pick on a higher level freestyle blade, which is why they are generally not recommended - but a low/intermediate freestyle blade (like the Coro Ace or Professional) is usually fine for most skaters at any level.. from beginner right on up to triples.
Any blade choice beyond that is simply personal choice - but beyond the physical differences of the radius and spin rocker and pick configuration, some blades like the gold seals are often chosen because the sole plate simply has more screw holes, making it more secure with the repeated pounding of triple and quad jumps. Not every skater doing quads uses those though - basic boot care (drying off, allowing to dry out between sessions) can prevent most catastrophic mounting failures, or at least identify them prior to failure, so you still see lots of skaters in other top level freestyle blades. It seems like we've heard a lot of failures at competitions recently (Gracie Gold, Jeremy Abbot, etc), but generally those kinds of issues are caught in advance and repaired quickly - it's relatively rare for them to become emergency situations right before a competition.
