Armory was looking very promising. Founded from from VC, active development, coin control, full node...
I still believe it is currently the most secure wallet but I have feeling using it may end on the wrong side of the (soft) fork as it happened with bitcoin 0.11when transactions had to be processed by online wallets.
segwit is coming 100%. soon. and I'am looking for a HD full node wallet that has active development and will validate segwit transactions.
The whole thing with 0.11 wasn't a soft fork, which is probably also why it took a little bit for armory to get up to date with that. There actually wasn't a whole lot of discussion about that upgarde, it just kinda happened and it pretty much took armory by surprise when the release came out.
I don't think that will be the case with segwit. Segwit was announced and has been planned for a while, so the developers know when it will come out and are probably already working on it. Since it is a soft fork, it has to be known ahead of time, unlike last time which wasn't a soft fork. I think armory will be fine when the soft fork happens.
Also, armory is still actively developed. Apparently it is now being developed for enterprise and is becoming more closed source, but the open source project of armory is still being worked on and will continue to be worked on by goatpig.
AFAIK armory is the only HD full node wallet. Supposedly Bitcoin Core has HD in the works, but it won't come out till at least 0.13 IIRC.
