I like a higher voltage relative to current: a higher rp operating point. 50mA/300V or 42mA/250V with 4k2 loads. I've wanted to try 60mA or even 50mA/350V for the 300B or higher dissipation 2A3 with a 5k+ load, but am moving on to something else with lower distortion.That is just my limited experience and preference and I totally get people liking something different.
Lots to try and learn.
Edit: in line with Paul's post above, I've included the load impedance for the various stated operating points.
