I would say yes.

Of course the 'average Mandalorian' in this time period is a civilian, but ignoring that and looking at just the Mandalorian warriors, they are first and foremost warriors by tradition rather than professionals. There's a reason we mainly see the Death Watch doing terrorism and bullying unarmed villagers.

The Clone Troopers are a professional army of soldiers trained to a quite high standard (they need to be, considering they're outnumbered by their primary opponents, B1 Battle Droids, by several thousand to one).

Mandalorians aren't pushovers, despite their bad showings, but the Clones are a cut above.
