As a former player coming back after ~6 years I love so much u/aer0_reddit 's Hydrosphere build but at the same time I'm overwhelmed by the supposed alternatives

After reaching level 50 I've checked the endgame build and, because it looks very expensive, I've also checked poeninja and found this build which looks a bit safer because that player seems to be using a shield and not 2 Void batteries like in his endgame build but don't know if it's also cheaper...

So, which one is cheaper and safer:

• Aer0's initial edgame https://pastebin.com/fRzVQEFp (12/9/22)
• that poeninja build
• Palesteron's edited version feat. Spell suppress and profane bloom - a build he also shared at some point https://pastebin.com/07np6gzR

From my understanding - if I go the shield path should I use items with armor and chance to block?
