Does the Note 4 have better signal strength than the Note 3?

Question

I have a note 3 that continually drops calls and bounces from 4 bars to 1 bar over the course of time with the phone being stationary.  I believe my problems started with the last software update (as documented in numerous forums) but both Verizon and Samsung give no credibility to problems raised on internet forums.  The people on these forums apparently "lack technical expertise" was my take on their explanation. 
So far they, Verizon, is following exactly the same course of action to try to correct my issues as other folks have stated they tried with tech support.  Replacement of the SIM card did nothing.  Software reflash is next followed by a factory reset with no additional apps allowed to download to the phone. 
I have not looked at a Note 4 nor do I know anyone that has one so I am reaching out for information.  What is the Note 4 running for software and if you owned a Note 3 previously did you experience signal strength issues where you felt you shouldn't have?  If you had, or have, weak signal strength were you able to compare it to another android phone on the same carrier to see if the problem was specific to you phone?
I understand the bars are not the best indication of signal strength but they are a quick indication.  Under the mobile networks I usually have -100+ dBm and 30 +asu.  If it is a software caused problem neither Verizon or Samsung knows anything about it which is good news because they should be able to correct it.  I have my doubts the people on the forums are the crackpots they make them out to be.  I suggested they are people like me who are desperate for help with a problem Verizon gave up on. 
If the Note 4 is better I know what to ask for when they hit the end of the road with me.  That will happen software and reset wise in the next week then I am off to "getting someone else's problem phone" sent to me for a swap.  Last time they tried this the junk phone they sent didn't even recognize the sim card! 
Thanks for any facts you can provide about your experience with the Note 3 and Note 4 as related to signal strength in both areas with strong and marginal service.

Answer 1

I have an iPhone 6 on Sprint for work and it stinks, I don't like the service or the phone.  Had an iPhone 5s prior and although I didn't care for it it was still better than the 6.
I had a software reflash done at Best Buy and a factory reset at Wireless world.  Reflash went smooth but I should have done the factory reset myself or had Best Buy do it.  It will take me days to get the phone back to where I had it.  Kies software from Samsung does backup the phone but you lose all the changes you have made to the Home screens and some other apps need attention to get them functional. 
Signal strength remains the same but need to use it for a few days to know if it still drops calls and breaks up.  If it does next on the list is running in safe mode for a few days to see if an app is causing it.  If the problem still persists I have the choice of replacing it with insurance, money out of my pocket.  Sending it to Samsung for testing and repair (if necessary), or having Verizon send a replacement refurbished phone.  Probably will go with the refurbished phone and hang on to mine for a few days as well.  If the refurb isn't any better I will return it and then send mine to Samsung. 
According to Wireless World the insurance company will pay me for my phone if I trade it in before a year is up.  May get up to 50% of full retail.  Not sure what to trade it in for if I go that route.
