C'mon, OP asked for some reasoning behind your choices people.
1) BitShares - Delegated proof of stake consensus enables decentralized governance via stakeholder voting for roles (witness, delegate, worker). BitShares is the first distributed ledger network to pay the devs that wrote it. Quickest block intervals (currently 10 seconds, soon to be 2), first platform to implement collateralized stablecoins without counterparty risk, on-chain decentralized exchange. The "industrial" blockchain. Engaged community and visionary dev teams (core devs in Blacksburg, bitsapphire in Kosovo, DACPLAY in China).
2) Bitcoin - tried and true, a crowd favorite. Also I like being able to spend cryptocurrency so although I don't hold onto very much BTC I do convert to it on the fly using gateways like metaexchange.info, shapeshift.io, and blocktrades.us.
3) Ethereum - cool project, good vision, looking forward to seeing what it can do when it stabilizes.
Honorary mentions: I've heard Qora is doing some cool stuff with AT. I also would like to learn more about the state of anon coins like dash & monero.
Thank you robrigo. This is what I was looking for, may I ask why you're not a fan of NXT? (coming from a guy who's only noticed its popularity via this thread)
I don't know enough about what is going on in the NXT ecosystem, but in general don't see any benefits to using its on-chain exchange over BitShares. It is slower, there aren't any market pegged assets, and it does not include on-chain governance features that I know of (electing roles via stake-weighted approval voting). Also, I think bytemaster makes some compelling arguments
here and
here as to why BitShares has a larger degree of decentralization over NXT. In general I'm not very interested in traditional proof of stake as the block rewards centralize towards the largest stakeholders, due to their increased chances to sign a block proportional to their stake.
BitShares will also scale to enable VISA NASDAQ levels of TPS; the next major release will support 100,000 transactions per second.
