Oh ok, thanks brehLike homey already mentioned M1 has fractional shares which means you don't have to pony up $1800 and $3000 respectively for google and Amazon stocks. Tdameritrade doesn't have fractional shares (that I know of).
Outside of fractional shares tdameritrade is pretty great. You can just sign up with them and use another account to do fractional shares.
Also I didn't find out about M1 until recently.
