SIMBA 1gbps home broadband

Recently SIMBA Telecom and WhizComms launched a very competitive 1gbps home broadband package at $20+ / month.
I am currently using MR at $40 which I am pretty satisfied with its data stability and CS.

My MR contract is ending soon hence Thinking to switch over to SIMBA /whizcomm for cost saving but worry about its connection quality and hidden catch.

Any one has experience of using these 2 telco broadband care to share?
Thanks
