Hands down, Dynasty Omega. By several bumps. They are an upper tier custom line and KM is merely mid grade semi custom.

It sounds like you have first hand experience with buying "cheap" kitchen cabinets - they just dont hold up more than 5 or 10 years. There are 2 issues with budget kitchen cabinets first is the structure/wood used..if not built correctly the wood dents and joints break with wear and tear. You can inspect for this before buying new cabinets. The finish is also very important and unfortunately it all looks good to start. THis is where you need to go with a reputable brand to ensure a good quality finish. Price for cabinets generally reflects quality so paying more will generally get you better quality cabinets. You can get a remodel cost estimate for your kitchen with the remodel cost calculators at www.remodelormove.com. To save on good quality cabinets select the finish and style you want and then check the brands that offer them then look for sales and specials many times you can find 10% off or more.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
