Becca Shimmering Skin Perfector vs Too Faced Diamond Highlighter

The Becca Shimmering Skin Perfector was well-received by reviewers at Good Housekeeping, a trustworthy source that performs unbiased hands-on testing. It did great in their "17 Best Face Highlighters for Your Most Radiant Skin Ever" roundup - they named it their "Best Highlighter for Smooth Skin", which, by itself, suggests that it's a noteworthy product.

As for the Too Faced Diamond Highlighter - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.
