Big hint that Vegeta (trunks saga) was considerably >> Piccolo (trunks saga)?

[ahill1]

Kuririn had yet to know Vegeta had SSJ and similarly hadn't seen Piccolo's improvements... And still seem to treat Vegeta as a bigger deal (even Vegeta got killed).

I don't think it has to imply anything other than Vegeta > Piccolo which is generally accepted.
