My opinion, what they lack in power they make up for in abusability. For example;

Use Gem-Knight Fusion to make Prism Aura.
Retrieve Gem-Knight Fusion.
Use Prism Aura's effect, discard Fusion to destroy something.
Attack.
Use Gem-Enhancement, tributing Prism Aura to summon the same one (semi-nomis are awesome)
Attack.
Retrieve Gem-Knight Fusion.
Use Prism Aura's effect, discard Fusion to destroy something.

If both attacks destroy something, it's +1, and you can retrieve Fusion anytime, so effectively it's +2.

Best part is half the fusions are compatible with [url="http://yugioh.wikia.com/wiki/Fusion_Weapon"]Fusion Weapon[/url].

They are fun, and can now run Gemini Spark.

I think Supervise is good too, since it can get Crystal out.

EDIT: Equip Supervise, use effect, use as fusion material, summon monster. More abuse!
