Best alternative to Coinbase for buying and sending a variety of crypto currencies

So I use Coinbase to easily buy crypto and then send it immediately (I carry a bank balance with them which allows for immediate transfer). I tend to make several small purchases over the course of a month. I like that Coinbase allows me a variety of different coins and I usually end up buying BTC, ETH, LTC, or USDT. Is there a different service with lower fees/spread where I can do the same? I'm considering Coin One ($30/month) to avoid the purchasing fees, but even then I'm still paying a 1% spread. Any insight appreciated, thanks!
