Flaxseeds are probably the most flavorless things I've ever tasted.

Chia seeds taste ok but you need to prep them by soaking which is a pain (or experience bloating).

All other seeds have more omega 6 than omega 3.

Funny - I feel the opposite about chia. Soaked and plumped is when I hate them. Dry on salads/etc. or just submerged in an active bowl I'm eating is when I like them most - the crunch adds texture to what I'm eating.
