The other half and I both had gloworm X2s- her main light, me for commuting. We both had problems with batteries and got through several replacements before eventually giving up. She now has a toro, I’m using my Maxx D for everything. So I’d suggest exposure. For what you want, an equinox and a booster cell?
I’d seriously recommend a bar/headlight combination though, you don’t flatten out roots like you do with just a head torch- figure out what you can get for your budget. I’d suggest a joystick and then the biggest bar light you want to afford (sticking with exposure- I’d also have 4th, a friend has them and they seem very well made and reliable).
