is there snobbery about what company one buys their conservatory from?

HI SOME OTHER COMPANY TO THE ONE I USES WILL BE HARDER , CLIPPING THE CORNER POSTS IN, GENERAL BECAUSE THE PLASTIC IS A LOT HARDER WHICH IS NOT A GOOD THING THESE CAN SLIP VERY EASY .. YOUR BETTER GOING WITH A PROFILE LIKE KOMMERLING , THEY ARE A SOFT PROFILE AND FLEXIBLE AND A FAR BETTER LOOKING PROFILE, ALSO A PLUS FOR KOMMERLING IS THE DOOR LOCKING SYSTEMS AND THE PLACING OF THE HINGES. THE INSTRUCTION ARE EASY TO WORK FROM , AND YOU GET THE BEST FOR YOUR MONEY NO ADDED EXTRAS ITS COMPLETE .GUTTERS .DOWN PIPES .ROOF TRIMS PROFILE .SELF CLEANING ROOF GLASS . ALL A RATED .ALSO NOW YOU CAN HAVE A GLASS ROOF , SO THE SOUND WHEN IT RAINS YOU CAN HERE YOUR SELF TALK, NOT LIKE POLYCARB PRODUCES .. I DON'T WORK FOR THEM I OWN A BUILDING COMPANY AND I JUST WISH FOR MY CLIENTS TO HAVE THE BEST , FOR THE RIGHT MONEY MANY THANKS COMPLEXBUILD.. FY5
