No both work fine and both have same apeture gun . The PT-22 is very hard to get so P19lug is easier to get ahold of but more work as you have to MOD the neck card.

As for PT-22( White White) they have the same aperture as P19lug( Red White) both are the same resolution and both are used in the 909 and Cine 9 units at the same time even!. Typically for soft edge the REG and BLUE are P19lug and Green is PT-22. However the 909 neck card is set up to take both tubes and I have seen a few 909 units that mix and match what ever was avail.
I am not sure if all 1209s units could take both tubes but the 1209 could not. You can make a 1209 have higher rez by putting in new P19lug and modifying the neck cards and I also mod the back end signal path, the P19lug as you know will need the KG grids tied to G1 ( I think have to pull my schematics) tougher to achieve the high rez or the focus will Bloom. I can send a schematic of what I do if you need it. Some people also use a 1 MEG resistor on KG the LUG to get the correct focus. I have not tested what procedure is the best for quality of picture. I know both work well.
The P19lug will look bad if you do not do this or will look like a lower res 1209 (Yellow White) gun.
I hope that helps.....
