I thought I share my observation on both these services - I would really like KeePassX/KeePass to keep improving hence this post.
I uninstalled this app and reverted to Lastpass because via Dropbox the password wasn't syncing despite the sync on Dropbox, the database wasn't updated on the phone app for new entries made on the Desktop
No Chrome Counterpart
This makes AutoFill and AutoSave a bit cumbersome as you have to use the standalone desktop app to go to URL and then fill your login credentials - LastPass makes it so easy here
No FillForm Input
Having no way to save your Address and banking credentials make it hard to fill forms, I could use Google Chrome Sync for that but I just find LastPass more secure
KeePass 2 under Mono
I could never get this working even following the step by step guide, the advantage of this at the moment would be for plugin support so I can integrate Chrome w/ Keepass
