to expand on this: it ain’t the bike you ride (though i’m sure some would disagree), it’s you / how it fits you.
my two road bikes are decathlon specials. i have an ultra af 700 for short “quick” rides: it has rim brakes and is fairly light for an alu bike. it cost me £550 originally, and yeah, while i slowly upgraded bits (wheels, tyres, crankset) and wore out consumables, it’s a lovely bike. however, the geo is a bit… uncomf for what i spend my time doing, endurance riding, and after doing a 600km ride and getting a lot of hand discomfort i bought another bike. i still ride it sometimes (though not at the moment) - i’ve racked up over 15000km on it 
my other bike is a triban rc520: disc brakes, endurance / comfy geometry, has all the mounts you could want - for mudguards and racks if you fancy, and clearance for big tyres. i fucking love it. i will be riding paris-brest-paris on this £729 steed while my mate i’m doing it with will be on a ridiculous titanium monster, yet we’re basically the same ability when it comes down to it. i have swapped the wheels out for something decent, and tyres too. added mudguards, it means i can ride it all year.
that said, you actually have to want to ride the bike you’ve got. if you don’t look at it and feel “yeah I want to go out for a ride” then you’re fucked.
