Wrong forum?
And what do you mean by better?
I'm already $500 in Mutual funds with 50% of my paycheck going into it every month but i was wondering if i should be in something else
Based on the context provided, I think you're asking the wrong question. It shouldn't be a question of mutual funds vs ETFs. It should be a question of what kind of investments do you want to buy. Stocks? Bonds? Is the fund or ETF well diversified? Is it indexed or actively managed (statistically, the better answer is indexed)?
Both ETFs and mutual funds can be invested in the same assets. For example, virtually every mutual fund that Vanguard offers has an ETF version.
Now granted, ETFs and mutual funds can have different expense ratios, as Lkxe pointed out. But ETFs in general can't be automatically invested (technically, it could work if they automatically invested using market orders. However, market orders are susceptible to skulldudgery and should be avoided when possible). Also, there is a usually small bid/ask spread that will reduce your overall return by a small amount. Hence I say that
once you've gotten a clear plan for what kind of assets you want to own (bonds, stocks, international vs domestic, etc) mutual funds are superior. But I emphasize that based solely on the context that you provided, it is the wrong question to be asking at this time.
