Dual Routers (Am i being silly)

HI All,

I've just had an upgrade to my cable internet connection to 350mbit+ (it peaks around 400mbit).

My second connection is a DSL 35mbit.

My current router only supports up to 250mbit (a Meraki MX64) and uses both broadband connections, general internet connections are routed out over the fast connection whilst the slower connection has several fixed IP addresses allocated to it, which I port forward various ports such as web server, home automation kit etc, and manages all of the Meraki VPN connections to my customers.

I also have a pair of Dell N1524 L3 Lite switches, one of which provides my VLAN’s in the house, and I’d like to keep it that way.

I’ve just taken delivery of a Unifi Edgerouter Pro, which can apparently handle up to Gigabit speed connections, and seems to be working fine on the cable connection.

My question is:

Should I replace the Meraki MX64 with the Unifi router completely?

Or is there any reason, apart from setup being more complex, not to use the Meraki for VPN connections via the DSL and the Unifi for general internet browsing via the cable connection?

My plan would be to setup route commands for the IP addresses for my customer networks on the Dell switch, my only planned usage would be for vpn traffic using the DSL connection.

Look forward to hearing any ideas, or reasons not to do what I am planning.

Thanks in advance
