According to this link ProCell are the same as Duracell industrial:

I've just been using 40 packs of GP Ultra Alkaline most of the time in my HR92's and DTS92E with no problems at all. They seem to last about 1 1/2 years in my HR92's, given that I have them all set in the more battery hungry Stroke 1 mode, and over 2 years in DTS92E's. (I've only changed the batteries in my DTS92's twice - and I've had them for 5 years!)

I've also tried the Varta Alkaline when the GP Ultra were out of stock and they have been fine as well.
While I'm sure that you can get longer battery life if you use something more expensive (especially Lithium) you'll pay a lot more for it so the cost to benefit ratio will actually be lower. HR92's etc aren't really as demanding as you make out - in my experience problems usually happen due to high contact resistance on the terrible battery contacts which frequently need bending to reset their tension. (I do this as a matter of course during a battery swap)
The only reason I can see to use Lithium is in a situation where you want to minimise battery swapping for example if you're looking after your parents system for them....
Whatever batteries you choose have a look at batterystation.co.uk - I've bought all my bulk batteries from them for years (including a big pre-Christmas batch for all the kids toys that would be consuming them..) and found them quite good. They seem to have every type you'll ever need and have been fairly quick with delivery.
