MM is hard to top; it's peak early LoZ (in an old man's opinion). It took a familiar engine, added two new major mechanics, and told the first really dark story.

Awakening is the one to play first, it'll set you up for later games nicely, and it was originally a Gameboy (not GBC game). It took the Zelda formula from the earlier NES iterations, and made a content-rich world.

I'd say save ages and seasons for last (when you get your carts!). They're amazing games that really show how far the GBC could be pushed, and are very much taking the awakening engine and doing wonderful things. The fact there is linked content between the two means you should also keep a pen and paper handy!
