Need help in mastering

[kimchi-tan]

I use FL in mastering now. Limiters are magical.

I've been practicing my mixing and mastering (which took a lot of trial-and-error) and some producers like to maximize the whole song, some don't, and some maximize the volume of the whole song and not care about any clipping.
I've been practicing and after a bunch of trial-and-error for the "avoid any clipping" style with compressing the final mix (instrumental and vocals) but I'm not sure which kind mastering is better.

Currently, I finished with types of mastering:

Which is better? Mastering #1 (the one on top) or Mastering #2? After looking at my music files with Audacity, a lot of producers (Vocaloid, UTAU, and Western) don't seem to fix any clipping, even if they're small (unless Audacity has a corrupt "output level" or something...)

Here are samples for #1 and #2 (it's a mediafire link)

Well, from a musicians point of view I would stick with version #2. Maximising and compressing until you can't "see" the song anymore isn't really a sign of good mastering, so I would avoid it.
