I can give a more proper opinion on the Skypad but in terms of superglides I can go only off word of mouth:
In terms of the superglides: they start off being great but become muddy really fast. From what I have heard, they are absolutely not worth the purchase. Hopefully it will be different for you, but chances are you will end up with muddy skates in the near future, so enjoy them while they last.
In terms of the Skypad: I am a former Skypad owner. If you never used a fast pad like this, I must say that it is quite an unique experience. The glide is incredibly smooth and very fast. Do not expect any kind of stopping power on the 3.0. I never owned the 2.0 but I heard it allows for a bit more stopping power due it's texture.
If you end up enjoying it, it can likely last you a life time, but I ended up shelving it.
Reason number 1 is that hair + dust on the pad, and/or on the skates will cause a terrible scratchy noise and also a horrible scratchy feeling. You will end up wiping your pad with a cloth/arm quite a lot to get rid of the gunk that causes the scratchiness.
Reason number 2 was that the lack of stopping power is quite jarring.
If you want an incredibly fast pad with a harder base, I personally rather recommend the Raiden MID. It will completely eliminate the scratching issue, although it will not last as long as the Skypad in terms of durability.
Another worthy contender to look into is the Cerapad, because I believe that it's ceramic coating causes this scratching issue to be less, but I personally cannot confirm or deny that. It is however a slightly more controlled pad according to word of mouth.
I do not want to discourage you at all to buy the Skypad if you are very keen on trying it, but be warry of the potential scratchiness that you have to deal with if it isn't properly clean.
