Best of Tier 1 is the first 5 (Is Opinion Based)
Best of Tier 2 also in bold. (Moved down from tier 1 as it is clearly not as good as the other tier 1's)

I'm sure if you take the time to look through the patterns you can find some really cool unique ones.
While making this tier list I found ones I personally really like.

Unfortunately just like most patterned based skins its really hard to find the exact ID on steam marketplace.

You can use chrome extensions to help narrow your search on the marketplace. I'm not going to recommend any because their is a fair few to choose from but I'll let you make that decision if you haven't already. Other market places (e.g FloatDB) are an option that can help also narrow the search. Just be careful of fake websites and sketchy marketplaces. Just be smart about it.
