I'm having a hard time deciding whether to carry FXAIX or FNILX in my Roth IRA.
For my brokerage accounts I have mostly VOO but I've heard that FXAIX and FNILX may be better due to their lower expense ratios.
I've seen some websites show that FXAIX performed a bit better but some people have said that FNILX has performed better which has me confused.
Are there any websites that provide an accurate comparison between the two, and which one performs better in the long run when taking into account expense ratios?
