Ledger X vs. Keystone Pro (BTC only)

Posted this in the Keystone subreddit but also posting here due to the greater level of activity in this subreddit.

Have been researching both and have three general questions:

1. Does the Keystone App allow for sub accounts within the same wallet? For instance, Ledger lets you have numerous BTC sub accounts that you can rename (Savings, Daily Spend, BTC for child, etc).

2. Does the wallet automatically generate a new BTC address for each transaction once an address has been used?

3. Has there been any history of hacks for either the KSP or Cobo?

Overall, for those of you that have switched, what has your experience been transitioning from ledger to keystone (I know, 4 questions, lol).
