First of all, Tidal has more songs than Spotify.
Second of all, Tidal offers a free 60 day trial if you sign up for Hi-Fi. While on Hi-Fi, you're able to switch your playback between all 4 different quality tiers. You can switch on the fly for A/B testing.
Going from Standard (MP3-128) to Premium (AAC-256 / MP3-320 equivalent) to Hi-Fi (FLAC 44.1/16) to Master (MQA 96/24) I can hear a major improvement with each step up in tier. To my ears, it's no small margin, either.
Is it worth the extra $10/month, though? Well, you could always get a couple of friends to join the Family Plan with you, which cost $30/mo. Split 3 ways, that's only $10/mo each, which is the same price as all the other services. If you can mange it, you can have up to 6 members in a Family Plan, and that's only $5/mo ea.
Also, you can use PayPal, and PayPal has a feature that lets you instantly send money to another PayPal account. So, you don't have to worry about collecting cash from your friends. You can even set it up to automatically send the money each month. You can also bill them. It really takes the sweat out of it.
Getting your friends involved means you'll be able to share playlists, talk about stuff, and get to enjoy a more fun and social listening experience. So, Tidal does not have to be expensive, if you're willing to share.
I recommend you start a 60 day trial, and decide for yourself. Get your friends involved, and ask their opinions. You never know, they might already have a subscription, and be willing to let you join their family. You'll be helping each other out, in the end.
