Not necessarily they are not, no. In our experience there is no correlation at all between the "size" of a betting site and its quality, using pretty much all metrics. The only time a small bookmaker is likely to be better is if you have a niche problem or query which can not be answered by standard FAQ guides then a smaller bookmaker is likely to have customer support willing and able to take the time to assist you on a personal level. In terms of most other things, the sports betting odds, the quality of the live streaming service, do they allow live betting, and the size has nothing to do with it. It is a bit like asking if a betting site with a blue logo better than a betting site with a red logo. The one place that the largest betting sites in Australia do possibly hold an advantage is in the range and depth of sports they cover, where some will have an absolutely massive range of betting options on each and every match.
