Avalanche is probably the biggest disappointment out of the whole bunch. They started out strong with a new consensus algorithm, and then they started hyping 'subnets', which turned out to be plain L1s with artificial restrictions on who can be a validator. Their tokenomics are so skewed in favour of AvaLabs and their early VC backers that they removed the pie chart from their website to conceal it. It's probably the most centralized out of all the wannabe Ethereums, with Emin singlehandedly calling the shots (how much needs to be staked to be a validator, whether subnet validators need to be whitelisted...), and they don't seem to have much of an idea where they're going (they went from bashing L2s and saying subnets are so much better to saying 'let's build L2s, ours will be so much better than Ethereum's'; they still haven't managed to build a bridging solution between subnets and they seem to have given up on that, given that they don't seem capable of competing with the existing interoperability protocols that treat subnets like any other chain, Avalanche-related or not). They also lost an 8-figure sum from the Terra collapse (Emin himself promoted UST after the depeg had started), which does not bode well for an ecosystem where they are still the only truly active entity promoting new projects. They're more than ripe for replacement by a standalone EVM-compatible chain that takes the only thing that's genuinely innovative about Avalanche, the consensus algorithms, and leaves the rest to the community (ie an actually decentralized project).
