MyRepublic 1Gbps broadband plans comparisons?

Hi all, I have been using the SingTel 1Gbps broadband band (along with an unused mioTV) that costs about $100+ dollars monthly. The current SingTel network I have been using hasn’t been great too i.e. download/upload speed are not up to par.

Thinking of getting MyRepublic 1Gpbs but what’s the difference between the TP-Link EC330 and ASUS RT-AX3000 plan(Price wise both are about the same)? And are there any hidden charges I may need to be aware of other than the fees stated in the web?
