The only reason for me to go XGT would be the XGT X2 tools, though I see that the 5" grinder would be a deal maker for some people. Most of the single battery XGT tools I would use are already available as 18v x2, (circ saw, rotary hammer) which is a platform I'm already using. For those high-draw tools (5" and 9" grinder, SDS-Max rotary hammer, table saw etc), I personally prefer Hikoki (Metabo HPT) Multivolt platform, simply because of the availability of AC-DC adapter, so I dont have to waste cycles on my batteries when using a tool for a longer period of time on a spot, with AC power available from a reasonable distance away.
