If you're going to say something as rude as that, you should at least take a moment to think about what you're asking. Unless they're testing the same region you're concerned about, their advice will be anecdotal, at best. Anecdotal advice is useless to you.
I said "no offense" to be clear I meant not to be rude. I simply prefer anecdotal real life experience to the number of bars. The bars show how strong the signal is for making phone calls not receiving data. I believe kch explained a more technical reason for why a 3G phone might get a better data signal than an LTE phone in a fringe area.
There are some phones that are well known to get better reception than others although all of the users data reports is really anecdotal. After all the signal is what it is. Some phones have a better antenna or radio software that gives them better reception. For example in the Android world it is well known that Motorola phones, especially older ones, are much better at drawing in a data signal than new Samsung models. The newest Motorola Droid only has one radio instead of 2 like older and other brand Android phones with VZW and are reputed to not be as good. I know from personal experience my RAZR Maxx HD had better ability to draw in data than Samsung Note 3. As a novice to Apple I was simply trying to delve experience of persons who might have a 4s and a 6 in the family.
I have never seen review that claimed phone x is better or worse at getting usuable internet in areas with weak signal but some phones definitely are better at it.
My wife who has a 4s doesn't care about many of the features of the iPhone 6. Her main concern is good battery life the the ability to retrieve data for internet in fringe areas. She asked me to see what I could find out before she upgrades. I am also considering switching to iPhone myself.
Believe me the last thing I want to do is insult someone trying to help me. I apologize for any confusion. Instead of saying "doesn't cut it" I should have again asked for persons with real life experience.
