That depends on your requirements. If you're comfortable with commandline
programs, I'd use gpg because it's still actively developed

Depends on the symmetric cipher used: if you use a 128 bit symmetric cipher
this becomes the weakest link. Anyway, brute-forcing a 4096 or 2048 bit RSA
key is still something that even the NSA can't do.

No. However, if you generate a RSA key with gpg it will be a v4 RSA key,
which are actually 2 keys, one for signing and one for encryption. This
is incompatible with pgp 2.x. If you want to remain compatible with
2.x users you need a <= 2048 bit RSA v3 key. If only GnuPG compatibility
counts a <= 4096 RSA v3 or v4 key will do, or a <= 4096 DH/DSS key.
