Playing PanO and feeling bad

Hello, I'm a new player. I have recently started PanO and assembled a nice force of mostly space knights :p

They look awesome, and I enjoy playing mostly HI. Will probably get a TAG or 2 eventually, but I really love the HI playstyle.

Learning more about other factions I an realizing Yu Jing seems to have everything that I have and more in the HI department, they got more choice/options and seem to get the same stuff for cheaper.

What I am asking is : am I missing something (and should feel better about my army) or should I just play Yu Jing if I'm set on playing HI focused lists?

I hope this isn't too whiny and gets removed.

I just started this game and already spent a couple hundred dollars on PanO models and probably close to a hundred hours painting them... and right now my enthusiasm for this game has taken a big hit as I feel I made a wrong choice/wasted a lot of time and energy...

Thank you for your help.
