In order to compare the films, you have to develop them to the same contrast index, preferably of the same scene. It takes a lot more than one roll of each to decide any real difference.
Since HP5+ is naturally a little bit lower in contrast than Tri-X, you have to adjust developing time, agitation and so on to compensate for that. YOU control the final contrast of the negative; it's a matter of working with your materials until you have the results you need. Get the final negative contrast the same in both films, and you will have a much better idea of what each film does, both from a tonality and grain standpoint. Print the negatives, at the same contrast grade. Adjust film developing time until both types of film print with similar contrast on the same paper.
Some said Rodinal like low temp < 20°C(~ 18°C) and longer development times(no stand development)...
I only have little experiance with TriX, and from that I prefer HP5+. It's easy to get EI 1600 from HP5+ f.e. in Emofin or 800 - 1600 in Caffenol-C-L.
#1 HP5+, EI 1600, Emofin 10 + 10 minutes 20 °C constant agitation.
#2 HP5+, EI 1600, Caffenol-C-L 75 minutes 20 °C semi-stand development
I like Rodinal, but it is probably one of the worst choices available for this purpose. 24 °C? No go.

Hp5 is a far superior film for pushing. Though every developer will produce different result, and it will be best if you use the best suited developer for each film, HP5 usually wins out in most cases. http://www.dr5.com/graphics/hp51000aad1.jpg
may I ask the lens you used for the second headshot. The lens is giving a very nice look for portrait/tight shots

I find the cupping of Tri-X ( Arista Premium ) to be a real pain, is HP-5 better in this regard, in terms of lying flat?
Yes ! At least according to my exprience.
