I do not know if this question to suitable here or not. I posted it as I think biologists can help me in this question. If not suitable here, then I am sorry for that.
I have written paper which I spent about 3 years working on it and it has nice findings and original sequenced data (deposited in NCBI). I submitted the paper to "Genome Biology" and I got editorial rejection but they offered to transfer the paper to "BMC Genomics". However, my supervisor refused this and suggested that we submit to "Nature Scientific Report". I tried to convince him to go to BMC Genomics because it is more focused journal and it is better for my CV, however, he said the second one is better because it has better impact factor and it is Nature! (Impact factor: 5 for Scientific Reports vs 4.04 for BMC Genomics).
What do you think as I am really confused which one to select?
