Always nice to be right ;).
Only some Cosmos chains can be on Osmosis at the moment, those that have enabled the IBC upgrade. So for now, the options are limited. As this list grows, it will have more options. In the not too distant future, Cosmos will finish the gravity bridge, which will bring pegged versions of ERC20 tokens into Cosmos. That will be significant.
Thorchain could be seen as a competitor, although the differences in their approach to cross chain are significant. More likely, they could complement each other, once Thorchain implements IBC. All it would take is an ATOM/RUNE pool, and a slick UI linking the two protocols together, to be able to move easily from one to the other. Thorchain wants to be the link between chains and eco-systems, and Osmosis could be one of the off-ramps to the smaller tokens available on it.
In terms of comparisons to ETH AMM's, Osmosis is most similar to Balancer (it is actually designed and adapted from Balancers source code). Gravity Dex coming early July on the Cosmos Hub (Cosmos chain itself) will be more like Uniswap by way of comparison. Both with much much lower gas fees of course.
Give it a try, be patient as the network is pretty busy and IBC transfers have had some glitches and reverted at times. When you are using your Osmosis Keplr wallet, set the fee to low (it is actually free for now) but hit "set gas" and change it to 5000000. Won't cost anything, but should push the transactions through without issue.
Have fun, hit me up if you need a hand with anything.
