Depends what you mean by "lockdown".

Thailand had curfews and flight bans etc so that's on my blacklist.

You want to be somewhere where you will not be locked at home, where "non essential" business aren't forced to close, where supply chains aren't cut, and where you can jump on a plane and leave any time if you don't like what they are doing. For me that was hong kong and it worked well, I'd probably just do that again.
