LTC confirmation is faster but it is not like BTC confirmation is that low, it is usually confirmed in 2h; the payment arrives in the wallet in seconds
There is no way LTC confirmation time is in seconds. it usually take 20 minutes for 6 confirm.
Faster confirmation is an advantage, but this advantage is not that great for average users. If you are buying stuff online, 1 hour of Bitcoin is not a problem because we will always need to wait few days for delivery. If you are buying offline at a local coffee shop with Litecoin, you still need to wait 15-20 min which is still inconvenient.
Generally, from user perspective, Litecoin is a little bit better. However it is not better enough to replace Bitcoin, BTC already have huge coverage. A crytocurrency need to have a revolutionary feature in order to take Bitcoin's crown.
