I used to use CoRE as well, and recently switched to webCoRE. If your needs are simple, and you’re already using CoRE, my opinion: just stay with what you’re using (albeit the latest & greatest version.) webCoRE is much easier to use and way more powerful, but again, depends on your needs.
Agreed with all the above. If you only have 3 pistons in CoRE, your move to WebCoRE should be simple. CoRE is dead, WeCoRE replaces it and is much more powerful.
