okay, if you insist. I've written for both, and they have a lot in common.
1) companies like stu4's hire anyone and everyone who passes a basic test, and many who don't. writers are then fined without being rewarded; often, they are fined more than they make. those who don't quit, become like slaves.
2) customer support at companies like stu4's is outsourced and staffed 24-7 with people who don't speak English well, and aren't very well-trained. they have fake names like "Brandy" and "Mike." they are available 24-7, but can't do much of anything to help anyone.
3) website design at stu4-type companies, which often does not differ at all between subsidiary companies and sometimes even competitors, is very well-done and efficient. however, often, there are so many orders, and so few writers qualified to do them, that orders simply tumble from the website with no writer. I'm not talking about a few; I'm talking about hundreds. I assume that the customer waits a few weeks during this process, and then gets nothing but frustration, and, possibly, but probably not, a partial refund. am I right, stu4?
4) like all term-paper mills, the "stu4 design" completely shafts its customers with contracts which leave them stuck firmly between a rock and a hard place.
5) in many countries, including the US and UK, a company could never get away with the first process listed above. #s 2-4 seem to be SOP worldwide, but sites like stu4's have that extra boost you can only get by having slaves.
ironically, I think it makes for tougher competition for Western-based essay companies, which aren't allowed to have slaves. in the end, it's not the customer who benefits.
