SD-WAN circuit choices : DIA vs Broadband

Hello all,

Looking to learn from other's experiences here for enterprise SD-WAN implementations, what kind of performance was seen with the circuit types?

1. Two broadband Internet circuits
2. One Broadband , one DIA

Traffic profiles mostly voice calls, O365, web browsing, file sharing, web meetings, limited video conferencing etc.
Basically trying to determine if two diverse broadband/non-DIA Internet circuits can be used to achieve the same level of service as a single DIA or MPLS.

Thanks in advance.
