are these worth the price?....

Over generic eBay strut bars? No. eBay generic strut bars will work just as well as the ones you linked to and will cost less.

When it starts making a difference is when you start looking into 1-piece bars (meaning the brackets and bar is all one solid piece), and 3 point and 4 point bars (in reference to strut bars only).

For the tie bars: in the rear a subframe reinforcement plate would work (and look, in case you care) better. In the front, an H-brace would work better. This is because H braces and subframe reinforcement plates don't have flex points.

Look into ASR subframe reinforcement plates, and NRG H-braces.
