From Note 4 to Z3, anyone?

Hey, I'm looking at getting a new phone. I am deciding between the Sony Z3 and the Samsung Galaxy Note 4. I have the Note 4 in my hands right now - I've had it for around 3 days so far - (SM-N910H) Exynos version.

I am not noticing any kind of lag or slow downs. I have loaded everything that I used to have on my LG G2. Is the lag going to come down the road or would I be experiencing it already? The reason I ask is because the last Samsung phone I had was the original Galaxy and I remember how bad the lag used to get the more you used it.

Samsung is notorious for future lags. Especially in future updates. I didn't think my device lagged, but within 2 months I saw major lags within multitasking and gallery, taking pictures. I reset it multiple times, it was always the same. It's just how Samsung works. Give you a great product, and then slow it down so you get a newer one down the line. I think ALL Androids slow down sooner or later, but I wholeheartedly believe that Samsung does it sooner than others. I base this on Samsung Galaxy Note, Note 2, Note 4, Galaxy S2, & S3
