Hi,
Yes they are both not really RF generator, nor low distorsion audio generateor but can help to align RF circuits, and with with audio, and also general purpose electronic. For my opinion, you need a frequency counter because both of them are not synthesized.

However TTI has a digital read out for frequency and amplitude and may be OK.

For the HP it is working up to 12MHz and has FM modulation, that is quite more better to work with radio that the TTI : you can work for 10.7MHz IF and FM demodulator. To use these kind of generator with radio and external 50ohms attenuator is usefull.

I Have an HP3312A because I like HP instruments....TTI seems to be a good equipement quite more modern...
