I know this isn't really a guide, per se, but there's nowhere else to put this, so... Yeah...

First of all, I'd like to show you guys this picture, which is a detailed breakdown between my 30:54 and Moustache's 31:45 (as we both use different routes):

If you take care to notice, the glitched route HUB movement is actually 7 seconds slower. The true difference is likely between 5-10 seconds, where glitched route is definitely not faster.

If you prefer doing HUB movement all in one go and are fine with menuing, glitching route is probably better for you. Linear route's HUB movement is more complex (mainly because the Ice Stone is a dick, entering Ice Cap is a little troublesome and getting to Knuckles can be a pain due to camera angles).

However, linear route is definitely faster, so if you're aiming for first or second place, linear route is the better route.

Camera routes for glitched can be REALLY funky unless you use the same camera (which you shouldn't, since camera control and camera routing has a large impact on consistency and movement/speed, contrary to popular belief [I leave the flame tunnel in Free Camera as evidence for this]). It flows a little better in linear, depending on how what cameras you use (if you're not using CCEF on PC disc or are on GC or DC, camera routes won't matter that much, though).

For some clearer evidence that linear is faster, here's a comparison between both routes (each part being segmented). The menuing and extra level entries was taken from CJ's PB, since his menuing is really good.

Here is also a comparison between one of Gpro's old console runs' HUB movement vs one of CJ's old runs' HUB movement:

Also, I DO want to point out that TAS route might be slower than Linear, but it's very hard to say at this point in time due to Gpro's game lagging in the Casino area and train station
