What is difference between reactstrap and react-bootstrap?

Question

I found two different bootstraps for reactjs

1. npm install --save reactstrap react react-dom
2. npm install react-bootstrap bootstrap

What is the basic and main difference between both?

I have been struggling with this myself and it is as @Besart Marku says, highly opinion based.

One thing that did make a diffirence for me is that reactstraps documentation uses state in alot of its code examples:

import React from 'react';
import { Button, Modal, ModalHeader, ModalBody, ModalFooter } from 'reactstrap';

class ModalExample extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      modal: false
    };

    this.toggle = this.toggle.bind(this);
  }

  toggle() {
    this.setState(prevState => ({
      modal: !prevState.modal
    }));
  }

  render() {
    return (
      <div>
        <Button color="danger" onClick={this.toggle}>{this.props.buttonLabel}</Button>
        <Modal isOpen={this.state.modal} toggle={this.toggle} className={this.props.className}>
          <ModalHeader toggle={this.toggle}>Modal title</ModalHeader>
          <ModalBody>
            Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

          </ModalBody>
          <ModalFooter>
            <Button color="primary" onClick={this.toggle}>Do Something</Button>{' '}
            <Button color="secondary" onClick={this.toggle}>Cancel</Button>
          </ModalFooter>
        </Modal>
      </div>
    );
  }
}

export default ModalExample; 

vs react-bootstrap uses functions and Hooks:

function MyVerticallyCenteredModal(props) {
  return (
    <Modal
      {...props}
      size="lg"
      aria-labelledby="contained-modal-title-vcenter"
      centered
    >
      <Modal.Header closeButton>
        <Modal.Title id="contained-modal-title-vcenter">
          Modal heading
        </Modal.Title>
      </Modal.Header>
      <Modal.Body>
        <h4>Centered Modal</h4>
        <p>
          Cras mattis consectetur purus sit amet fermentum. Cras justo odio,
          dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac
          consectetur ac, vestibulum at eros.
        </p>
      </Modal.Body>
      <Modal.Footer>
        <Button onClick={props.onHide}>Close</Button>
      </Modal.Footer>
    </Modal>
  );
}

function App() {
  const [modalShow, setModalShow] = React.useState(false);

  return (
    <ButtonToolbar>
      <Button variant="primary" onClick={() => setModalShow(true)}>
        Launch vertically centered modal
      </Button>

      <MyVerticallyCenteredModal
        show={modalShow}
        onHide={() => setModalShow(false)}
      />
    </ButtonToolbar>
  );
}

render(<App />);

Im not giving an answer saying one of these is better than the other,its a preference and for me personaly I vent with reactstrap since I tend to use classcomponents more than Hooks so having finished examples that I can tweak with minimal effort did the trick.
