The suggestions are purely based on the personal experiences and budget flexiblity of the OP i would believe. Putting in my personal experience , when in 2016 i was looking for my first decent HT system with AVR + 5.1 setup , I started with a budget of 40-45k and had auditioned the 3072 which did not excite me during the audition and I decided to visit Profx. There I auditioned the Polk TL1600 + Yamaha AVR setup which sounded heavenly.
Recently when i auditioned a few bookshelfs and saw what they are capable of i ended up upgrading my setup and noticed a Day&Night difference in the surround environment capabilities. Others would have probably experienced the same moving from a Taga 606 to a Elac/QAcoustics based setup and hence are recommending the same. If you have the flexibility its always better to go for whatever you can commit to at the moment and then get other items in future but if you are hard on the fact you dont want to cross 1 lakh for next 3 years then it makes sense to go for the best available options in that budget.
For your above scenario Taga 606 certainly would sound like a definite upgrade over the HT3072 , never heard soundbars till date so wont comment.
