I use Reroll but not Modify. I think it a rather big design flaw that you have the option, but I instead choose to see it as an alternative way of adjusting the difficulty of the game than the actual difficulty setting, which simply just changes the monsters’ hit points, which is rather boring.
So if you just want an easier game, max all or some of their stats. If you want a challenge, stick to Reroll. This will give an entirely different gameplay experience even if you keep the difficulty level at Veteran.
The difference is rather dramatic. Like the famous rope guild encounter in Pool of Radiance. If you play with Rerolled characters it will be almost impossible to beat as a low level party, and you will need to return to it later. Presumably what the developers intended. But if you max all your stats, you may be able to breeze through the encounter and it will feel like one of the regular hobgoblin encounters for your Rerolled party. Anticlimactic to some, power fantasy to others.
Also keep in mind that if you not only max your starting stats, but also savescum to get better level up hit points, the difference becomes even crazier.
I recently completed the Krynn series with Rerolled characters and in the entire series there were only two battles where I had to reduce the difficulty setting to beat. They were some nasty draconian/dracolich/beholder encounters by the end of the third game. I haven’t played Pools of Darkness, but have heard some of the late encounters are really tough if you don’t have high Dex scores for initiative. But if true, you could always raise them once you get to that game. A bonus of the built-in difficulty setting is that you can always drop it for one particular encounter and then raise it again after.
AFAIK the reason for the Modify feature is so you could recreate your P&P character rather than to simply max out your stats. But you could use Modify to make an uber party that quickly ploughs through the games to experience the story. Though I would argue the combat is the games’ main point, as the engine isn’t built for intricate narrative and dialogue.
Ultimately it’s up to you and the experience you want. If you choose reroll, keep in mind there is a minimum you want for your character’s prime stat, depending on his class.
Oh, and if you are unsure if the games will be too tough, you could always start with Reroll. Then if it turns out too hard overall, use the Gold Box Companion to buff your stats and HP.
