Network Design with XGS 4300

Question

Our network will consist of 5 access switches connected to a layer 3 core switch connected to a XGS 4300. We will have several VLANS consisting of computers, VoIP phones, security cameras and card access readers. Total users will be around 100. We are fully cloud and no longer have any servers so no DHCP or DNS server. It appears my options are to use the core switch as layer 2 and let the XGS 4300 handle the routing, DHCP and DNS or use the core switch as layer 3 and let the switch handle DHCP. Does anyone have a recommendation as to which setup will give the best performance? Am I missing any other options?

Hi PMIAdmin, 
 "In my own opinion", I would prefer the Core Switch as a layer 2 and let the XG handle the routing, DHCP, and DNS 
 Since it's a small number of users, not many resources will be taken and I only need to manage 1 Device for configuration. 
 
 But If I plan to expand more users and services, and plan to change the config most of the time. I'll go with the other way. 
 As stated this is my own opinion, feel free to disagree
