Statistically speaking, there's no doubt about what you are saying Rogue. A Bold nature (and Calm too in this case) benefits more from the +10% increase. The only way to capitalize the max amount of stats from a pokemon is to use a positive nature on the highest stat, but if everyone does it, everything becomes predictable. There would be no point in running a Calm Thundurus, a Bold Politoed, a Jolly Kang and so on, because we would just waste stat points.
I just wanted to say, in my opinion, that Suicune should offer Tailwind + Snarl support while always being able get easier kills on something you don't want for more than one turn on the field.
A Modest Suicune with 148 EVs in SpA is able to OHKO 4 HP LandT, Garchomp and M-Mence, while always 2HKO Bisharp. A Bold one would need 244 EVs to achieve the same goals. Is a Modest Suicune able to survive the strongest attacks? Yes, because we still can invest 252 EVs in HP and 108 EVs in Defence, still reaching high stats (in particular 207 HP and 149 Def).
I'm just using Suicune's natural bulk to achieve more goals than a Bold one. I don't want to have Suicune on the field forever because once you get a Tailwind and maybe a Snarl if its needed, if i need more offensive presence i switch it out, but i know that when LandT, Garchomp and so on enter the field, i have a solid option to counter them.
In addiction to this, you can always have Intimidate support to virtually increase your Defence, but SpA is something you have or you don't have.
