The only real downside of muun imo is when sending lightning payments OUT, there's higher fees due to their implementation of submarine swaps. Lightning in is fine/normal.
It's great as a recieving wallet and it combines your lightning and onchain balances into one unified amount.
Protip: It's also really good for consolidating your utxos. When you have like 1-5m sats in your muun wallet, you can send it out in one big utxo to cold storage. A great way to consolidate all those nostr zaps alongside your relatively small onchain transactions.
