TopGen is a badass.I use it for a while and the results are getting better in SERP.Don't expect to be nr1 in a month.There's alot of thinks to take care to stay on top of SERP (gain traffic and here's alot of techniques to achieve this).I don't use DPGP anymore because I don't take the risc to get banned from SE...i think TopGen is enough to get indexed and have fresh content .The other problem is the domain age and ISPs.If you are using a cheap ISP and you have a new domain you need lot of patience to make your site popular (lot of work to do...).TopGen is doing a great job but I think is not enough if you have a big competition.Using BH and WH techniques I think is the best solution to beat the competition no matter how big is it ....in time.TopGen and PSubmitter are great tools...to boost your site in SERP but from what I have read here on the forum people expect to be nr 1 in SE in notime......you wrong....without a good understanding of the way that SE is working you never be on top.
