I should simply stick to Lubuntu huh?
That is your choice. Using a rolling release of Debian (the base of Sparky) means that you are tearing out and building back up the structure of your system. It is somewhat like living in a house with always one room under construction. https://release.debian.org/transitions/
The Perl 5.22 room is almost done- it went pretty easy and on budget. But the libstc++ room last August required users to get extra help online, to be very careful with dist-upgrades and cost more time than expected.
The "zoning people" will just pop in during your room construction = dist-upgrades on the command line and use terse words, (short difficult and in their own usage of the language) and tell you about changes to the "electrical system" or "plumbing system" Typing "q" makes their notification disappear.
For non-rolling distros, when there is a change from "weasel" to "tapir" (Ubuntu) or from one Toy Story character to another ( Wheezy to Jessie to Stretch in Debian) there is a long list of changes that you probably don't read closely. For Testing, you get the list of changes one at a time, because linux lets you know the architecture and design of the system.
Stretch testing will enter a quieter phase in September 2016 and an even quieter phase in November 2016. https://wiki.debian.org/DebianStretch
If you feel that it is too difficult at this time or that you need a very stable system, Sparky based on Debian Tesing might be too much. But as your linux skills increase, you might want to stop back again in the Fall.
