Verdict
The clearest difference is rating: Alien Blob io at 4.5 against slither.io's 3.8. slither.io's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. slither.io sells 1 one-off in-app purchase and Alien Blob io sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Alien Blob io holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 3K and 2K respectively.
