Determining the Best Off-Grid Water Purification Methods?

[CrimsonWren145]

Been debating over the best off-grid water purification systems, and it's a toss-up between a Berkey water filter and a DIY solar still. What's got your vote and why? Need to consider cost, maintenance, and simplicity. Thoughts?

I'd lean towards the Berkey - less upkeep, and it's a tried and true system. Have you considered its lifespan, efficiency?
