Which Piloswine should I power up?
With the new Sinnoh Stone, and Gen4 evolutions coming, which Piloswine should I power up taking into consideration the incoming Def/HP rework?
Piloswine 98% - 15/15/14
Piloswine 96% - 15/13/15
So what is more durable? 15 defense and 14 HP, or 13 defense and 15 HP?

You gain energy from taking damage, so lower def = possibly more damage taken = possibly more energy = possibly more charge moves done faster. The key word is the "possibly". It's extremely rare that you gain any kind of an advantage this way and probably more likely that the additional damage will cause you to faint faster.
Assuming A/D/H order, the 98% is better. Higher overall IV and HP IV is less valuable for Piloswine and Mamoswine, being low def/high hp pokemon. The rework does not change this.
Just don't power them up yet. Ice is not a necessary attacking type at the moment, so you should simply wait until investing anything valuable.
None of them.
Wait until it actually can be evolved. Same may be said for the HP/DEF rework. It was announced as coming soon like a month ago and still there is no confirmation that is coming anytime soon.
I personally will not invest any dust on my 100% or my level 35 luckies until the evolution is here.
