All Hunchi variants are a lot more flexible than most people give them credit for. Depending on play style and desired role you could probably find a good fit with any of the variants. I chose the 4G/4SP/4P variants as I feel the 4H and 4J are hybrids of these platforms. There wasn't really anything I could do with 4H or 4J that I couldn't with one the 3 I chose. There are a lot more builds out there. How effective they are depends on if you play to their strengths. These are just some possibilities to give you some ideas.
If you are buying only 1 and want the best medium brawler then the 4SP is probably the best (if there is a "best") especially with 2xSRM6s (if you get use to hitting moving targets with them). The 4SP can also do ranged setups with LRMs, light hunting with SSRMs or a combination of the two.
4P can be equally deadly in a brawl and is great for taking out lights in stock configuration (4SP works great as a light hunter with 5ML 2SSRMs, but with ECM the 4P probably has the upper hand now). You can also have an almost 4G setup using one PPC for direct fire support or snipping and the rest ML or SL, or 2LL for fire support the rest SL etc.
The 4G is probably the best direct fire support Hunchi. If your going for just one ballistic (like AC20) then the 4H is better as it can support an AC20 and 5ML. But the 4G can support a UAC5 with an AC5 or AC2 for much greater DPS to shred opponents much faster while your assault absorbs the damage. The AC2 is also great for harassing Snipers and LRM boats at distance forcing them to take cover so you can close with your team. The continued rocking effects of this setup also gives you and your team some protection. Some go for 3xAC2s but I personally find it to be too much heat and too low burst damage.
The 4G can make a great light hunter too. You can put in a fast engine 3ML and an LBX10 (give or take an AC2 for sniper harassment) and shred those lights legs. This is especially effective now that ECMs are rampant, you're not streak dependent so it works great.
In short, all else aside, I find the 4G and 4SP the most fun (4G even more so). Which is what matters the most after all. But the 4SP (and 4P) I felt required less skill/time to become proficient with.
P.S. on the matter of Artemis, I use it on my 4SP. It doesn't compensate for bad aiming/piloting, but it does help reduce the spread of damage in the 150ish-270m range. If you're face-hugging your enemy, not much of a difference.
