Unfortunately I know what you mean. I'm in Orange County, CA and I can only stream music reliably if I'm connected to band 41. Band 25 and 3g is just awful for streaming with 3g almost unusable for any data related tasks.

I haven't had any issues lately with streaming, but it has gotten better. I usually stream Pandora while at the gym with no issues. but a few years back, it was unusable. I commute to OC everyday.

I have a UNLOCKED iPhone 6+ from VZW could I put the phone on Sprint? Will SPARK work?

Check out Robert's statement below 

 

However, the biggest limitation will be Sprint Spark compatibility, as Apple devices for other providers tend to not support LTE Band 41.

 

Verizon will not work with Spark Band 41.
