Allocating brokerage dollars evenly?

First preface that I have a yearly maxed 401k, IRA, and "proper" emergency fund. Every paycheck I put $100 into my brokerage with Chase (which doesn't have auto-investing like robinhood does). I have four holdings:
VOO
SCHD
MAIN
EPD

Each of the above have their benefits, but i have just been allocating $25 to each of them when the $100 hits. Should I be putting more thought into how i am allocating to these four?
