Is it the same? It's weight loss no matter the amount, so yes, in a sense.
I'm actually the perfect person to ask this question to. I was effortlessly naturally thin up until depression struck a year ago. I used to eat at least 3000 calories a day, but since I'm tall I stayed thin anyway. I'd walk a few times a week and maintain a great figure while pigging out.. I ate like someone three times my size would eat.
When the depression hit, something changed and I gained about thirty-five pounds. My best friend and I decided to lose weight together two months ago. She's got a longer way to go than me, and her weight seems to melt off in comparison. Do I think it's easier for her? In some ways, yes. She eats a lot more than I do and loses a lot more than I do.
I have about twenty pounds left to lose now, and as a person who was effortlessly thin while eating a gross amount of calories before, it's as hard for me as it is for her. When I stopped fitting in my clothes at first and started getting stretch marks, I had such self-loathing that I could barely get by day to day. I'm attractive too, and it's always been a (sadly too big) part of my identity. So as someone who has never had more than a (relatively) "few" pounds to lose, I found gaining that amount to be hard on me and losing it to be even harder.
Losing that last little bit is a "lifestyle" change as much as losing one hundred pounds. Weight loss always is if you're doing it the right way.
Be understanding of your friend, don't minimalize her struggle. You never know what's going on in her head, and at the end of the day you two just need to support each other. My best friend and I are always happy for each other, and our goals are very different. Also keep in mind that people are rarely as critical of others as they are of themselves. Her extra ten may look disgusting on her, but I'm sure she's not even paying attention to your extra thirty in remotely the same way, if at all.

Hope that helps.
