Fidelity ETF

Does anyone here own Mutual funds or ETFs from Fidelity? They copy the S&P 500 and i was wondering if anyone invested in the Fidelity ones or would you guys recommend just sticking with the usual ones on the Nasdaq like vanguard? I am new to investing and i want to invest in Mutual funds / ETFS

Edit: I currently have 4 Fidelity Funds - FXAIX, FZROX, FZILX and (FREL im not sure on this one but im still up a tiny amount) The first 3 seem to be doing good I also have VXUS, VTI, VOO, VGT, and SPY
