I finished my two years on POSB SAYE. Now I'm looking for another service that has bigger return. Should I just transfer my funds to SAYE or other service and continue saving there?

I started POSB SAYE two years ago to save money transfering 1K a month. Now I got my bonus but I want to try something else. I've ready about Syfe Cash + and want to put my money there. Should I just transfer all my money there (around 24k++) and then make a monthly savings of 1k a month (just like on SAYE). Would that be a better choice thatn the POSB SAYE or is it risky? Should I try the DBS Digiportfolio (or multiplier account)? I don't want any risk and really just want to grow my money.
