In terms of maximum current, this pack holds its own against the other XC packs, being within 90% of the output of the XC5.0 HO, similar output to the XC4.0 and way higher than the XC6.0 (which is the lame duck for current).
Note that the HO branding is a little bit weird in the M12 line since all battery packs use 18650 cells and, because of that, the increased output in the HO packs is pretty modest compared to other packs in the same form factor (i.e., CP or XC). This is different to the M18 line where regular packs use 18650s but HO packs use 21700s (and FORGE use tabless 21700s for the 8 and 12Ah or pouches for the 6Ah).
To be a bit more quantitative about it, here are the capacities and maximum rated output current of all of the M12 lineup. These numbers are based on the cells used in, what I believe are, the most recent versions. However, the cells sometimes change over time (presumably due to performance or supply-change issues) and so don't hold me to these numbers.
CP1.5 - 1.5Ah, 23A
CP2.0 - 2.0Ah, 22A
CP2.5 HO - 2.5Ah, 25A
CP3.0 - 3.0Ah, 20A
XC3.0 - 3.0Ah, 46A
XC4.0 - 4.0Ah, 44A
XC5.0 - 5.0Ah, 50A
XC6.0 - 6.0Ah, 30A
For full disclosure, I personally try to stick to XC5.0 HO for the larger packs to get the extra capacity, but you definitely pay more $/Ah for those packs.

Seems like the 5.0 HO are the best option, holding out for a deal on them as I have a bunch of 1.5 - 2.5's already.
