1) I just picked up a Taigen Jagpanther and KV1..
2) A Matomart Tiger 1.
3) And also a HL Leopard 2A6 off Amazon.

I would Rate their Quality and Finish in the Order Listed.
Taigen may be characterized as an Upgraded HL.
However from What I've seen, Taigen's Upgrades are Significant.
And Taigen's Customer Service is Top Notch.

HLTx are pretty much Junk.
MatoMart Tx are a bit Better but basically HL Dressed Up.
Taigen Tx more closely aproach Hoby Grade, Are easy to Rebind to your Rx,
and while the function is basically similar, the quality seams to be the Best of the three.

Hope this answers some of your question.
