I can provide some info about TD, Simplii, Tangerine, EQ, and Wealthsimple (more of an investing service than a bank):

Online Banking Experience:

• TD: Webapp works but is not pretty. App is more polished.
• Simplii: Webapp is similar to TD in lack of polish. Mobile app is similar to the other two above.
• Tangerine: Webapp is a bit better than the above two. App is more polished.
• EQ: Webapp is a bit more polished like Tangerine. Mobile app is a little worse than the above but still fine.
• Wealthsimple: Probably the best webapp and mobile app experience.

Credit Cards (Ease of Use):

• TD: Many credit card options and can automate payments for it from any institution (I believe).
• Simplii: They have a free card that has 4% back on restaurants which is pretty cool. Can be automated from other institutions.
• Tangerine: They have a very cool free credit card (2% back on 2-3 user selected categories). Annoyingly though, you can't automate payments using another institution.
• EQ: No idea about credit cards.
• Wealthsimple: I believe they just released a new credit card. No idea how good it is.

Fees:

• TD: They have an account that if you keep a minimum $5000 in it, there are no fees and you get some extra perks (free premium credit card, etc.). Other than that, the free account with no minimum is pretty limited.
• Simplii: Free accounts and credit cards.
• Tangerine: Free accounts and credit cards.
• EQ: Free accounts. Not sure about credit cards.
• Wealth simple: Free account. Not sure about credit card.

Etransfers:

• TD: etransfers have a fee but is waived if you hit the minimum in the account.
• Simplii: free
• Tangerine: free
• EQ: free
• Wealth simple: no idea. Don't think they allow etransfers.

Security:

• TD: Security is okay. They have a standalone authenticator app, so they need to step it up, but sadly they are still one of the better ones in Canada.
• Simplii: Meh security. Normal passwords and SMS 2FA.
• Tangerine: Awful security. Your password can only be a 6 digit numerical pin. Thankfully they require 2FA but only using SMS.
• EQ: Meh security. Normal passwords and SMS 2FA.
• Wealth simple: Good security. TOTP available and I believe passkey is here or coming? Not sure about that last part, but I wouldn't be surprised with how ahead of the curve they are in this area.

Rewards:

• TD: Rewards depend on the credit card here.
• Simplii: Rewards are just in credit card.
• Tangerine: They have various rewards throughout the year. Usually temporary boosts to the interest on their savings account.
• EQ: Nope.
• Wealth simple: Nope.

Investing:

• TD: No idea.
• Simplii: no idea
• Tangerine: no idea
• EQ: Can buy GICs here but no idea otherwise.
• Wealth simple: The best since it's an investing service.

Misc:

• TD: Great customer support and very established. Has lots of options for accounts, cards, etc.
• Simplii: No in person access.
• Tangerine: No in persona access. Security is abysmal but the other services are pretty good.
• EQ: Typically has the highest interest rate of all Canadian banks for the savings account. No in person access.
• Wealth simple: Great for investing and a good service!

What I do: I have my everyday banking with TD, savings with EQ, and investing with Wealthsimple. When Tangerine gives a promo, I move my savings there until the promo expires, then I move it back to EQ. I have credit cards with a bunch, but the one I'm considering ditching is the Tangerine one since payments cannot be automated through another institution.
